Streets in the British Overseas Territory of Gibraltar are represented by road signs as in the United Kingdom.  As of 2007, Gibraltar has a network of  of roads.

History
Most of the traditional Spanish names for the streets in Gibraltar were established before 1870 when the local police added signs. The new signs did not refer to the older names and this has led to a long running confusion. The deputy librarian of the Garrison Library issued a list of the streets in English and Spanish in the Gibraltar Directory of 1890 to assist.

Castle Street

Castle Street (Calle de la Cuesta or more popularly Calle Comedia) runs to the east of the town, to the north of Flat Bastion Road. It is divided into several parts which are named Upper Castle and Lower Castle Road.

The street is also known as Calle Comedia as in the nineteenth century the street had a theatre in what had been a real tennis court which was used for entertainment. This theatre was in use until the Theatre Royal was built in Governor's Parade.

Cathedral Square
The Cathedral Square, a square in the city centre is the location of the Church of England Cathedral of the Holy Trinity which stands to the eastern end of the square. Other features at the square include Duke of Kent House, which is home to the Gibraltar Tourist Board, the Bristol Hotel a children's play park and a boulevard lined with nine cannon overlooking the harbour. Fortress House is also located at 9 Cathedral Square one of the oldest and largest colonial houses on the Rock.

Devil's Gap Road

The Devils Gap Road (Escalera de Monte in Spanish) lies between its junction with Flat Bastion in the northern direction and the Upper Kiln Road in the southern direction. Also known as the Union Jack Steps and Referendum Steps, the road was originally painted in 1967 to celebrate the Gibraltar sovereignty referendum of that year. In August 2011, the steps were repainted in red, white, and blue by volunteers intent on restoring the Union Jack.

Devil's Tower Road

Devil's Tower Road is a major road of northeastern Gibraltar. It runs south of Gibraltar International Airport, extending from Winston Churchill Avenue east to Eastern Beach Road. The road was named after Devil's Tower, a 17th-century watchtower which formed part of the northern defences of Gibraltar as mentioned in the Treaty of Utrecht. In 2007, the Government of Gibraltar announced plans for a new airport terminal and diversion of traffic along Devil's Tower Road, with a new access road that would link Devil's Tower Road and the Gibraltar-Spain border. The new access road would pass through a tunnel at the eastern end of the runway. By 2011, Devil's Tower Road had been converted to a dual carriageway, with elimination of on-street parking, and the government had announced a plan to rename the road as North Front Avenue. This decision was met with protests from the community. In August of that year, the Government cancelled the contract with firm OHL for the tunnel and access road for "failure to comply with the terms of the contract." The project had been on hold since December 2010. In 2012, OHL brought legal action against the Government. In August of that year, the tender process for the tunnel and access road was started for the second time. Devil's Tower Road is home to North Front Cemetery, the Gibraltar Memorial, the Gibraltar Cross of Sacrifice, St. Theresa's Church and Devil's Tower Camp with its Princess Royal Medical Centre.

Dudley Ward Way

Dudley Ward Way is a  long road tunnel through the south-eastern part of the Gibraltar. It is named after Sir Alfred Dudley Ward, Governor of Gibraltar from 8 June 1962 to 5 August 1965. The road running through the tunnel links the eastern side of The Rock (including Catalan Bay and Sandy Bay) via Sir Herbert Miles Road, with Europa Point, at the southern tip of Gibraltar via Europa Advance Road. Dudley Ward Way was built during the 1956-1968 period by the British Army. After the end of military tunnelling and the departure of the Royal Engineer tunnellers the maintenance of the tunnel was transferred to the civilian authorities.

Europa Road

Europort Avenue

Europort Avenue is built on reclaimed land and buildings include McDonald's fast food, Morrisons supermarket and St Bernard's Hospital.

Flat Bastion Road

The  long Flat Bastion Road runs north–south from Devil's Gap Road and becomes Gardiner's Road before entering Europa Road, to The Llanito name for the road is Cuesta de Mr. Bourne, and used to be known in Spanish as  ().

Of note is the Flat Bastion Magazine—now a geological research facility and exhibition centre that forms part of the Flat Bastion. The Gibraltar Public School opened on Flat Bastion Road in 1832 and served as a free institution for impoverished children of all denominations. In 2009 a government initiative proposed putting an additional 104 public parking spots on the road. In 2010 there was public criticism about the lack of parking on the road as the government had removed existing parking before constructing the new parking spaces.

Glacis Road
Glacis Road is a road in northern Gibraltar, the southwestern end of which is the junction with the Waterport Roundabout, where Waterport Road and Queensway Street also intersect. From the roundabout, Glacis Road extends to the northeast. At its mid portion, the road intersects with Bayside Road, at which point it changes course to a southeast direction. Its eastern end intersects with Winston Churchill Avenue. The North District office of the Royal Gibraltar Post Office is on Glacis Road.

Grand Casemates Square

The square is lined with numerous pubs, bars and restaurants. and acts as the gateway into Gibraltar's city centre for most tourists. In the past, public executions used to be done at Casemates Square of this street. Main Street extends southward from the square. The area at one time constituted part of the Spanish town Villa Vieja. It was later referred to as Casemates, a term which refers to an arched chamber in a fortification. The damage to this area during the Siege of Gibraltar (1727) was sufficiently severe that the British opted to demolish the buildings and make an esplanade.

Irish Town
Irish Town is one of Main Street's sub-districts running parallel to it, from Cooperage Lane in the north to John Mackintosh Square in the south. It was named in the early 19th century when Gibraltar was split into differing quarters although its original name was Calle de Santa Ana after a hermitage on the street. The name irish Town had been attributed to the merchants who lived there but research shows this to be untrue. A credible reason was that an Irish regiment was barracked here. A more colourful explanation is that it named after the ladies who supported that regiment as the street had a reputation in the 18th century.

John Mackintosh Square
John Mackintosh Square is referred to colloquially as The Piazza. While it has had a variety of names over the centuries, during the 19th century, it was known as Commercial Square.

Winston Churchill Avenue 

Winston Churchill Avenue is a northern 1.5 km arterial road which is the only road in and out of the territory, connecting it with Spain. Once the customs are crossed, the avenue becomes the dual carriageway () CA-34 (former national road N-351). The road intersects the runway of the Gibraltar Airport; movable barricades close when aircraft land or take off. In 2009, the Government of Gibraltar announced that a new highway will be built in order to avoid the crossing of the airport runway. The new road, a dual carriageway, will link the customs checkpoint with Devil's Tower Road, crossing the airport runway underground, through a 350-metre tunnel.

Bell Lane runs between Main Street and Engineer Lane. Other streets include George's Lane, Prince Edward's Road, Lime Kiln Road and Governor's Street.

New road proposal
A new  road connecting Gibraltar to Spain with access to the airport was proposed and the contract was awarded in 2009 to OBL at a cost of €35.78 million. This road would bypass the current road which crosses the runway of the airport. The planning and design of the road included two lanes in each direction, linking the border with Spain to the Devil's Tower Road. It would also provide links to the Eastern Beach Road and Road Catalan; two bridges for cyclists and pedestrians a were also proposed parallel to the highway.
