A four funnel liner, four funnelled liner or four stacker is an ocean liner with four funnels.
 The SS "Great Eastern", launched on 31 January 1858 (a full 40 years ahead of any comparable ships), was the only ocean liner to sport five funnels.
 As one funnel was later removed, the "Great Eastern", by default, became the first ocean liner to have four funnels.
 However, after the Great Eastern became a four funnel ship she never carried passengers so really should not be considered the first four funnel liner.
 The SS "Kaiser Wilhelm der Grosse", launched on 4 May 1897, was properly the first ocean liner to have four funnels and was one of the first of the golden era of ocean liners that became prominent in the early- to mid-20th century.
 The most famous four funnel liners are the RMS "Titanic", which sank after striking an iceberg on her maiden voyage on 14 April 1912, and the RMS "Lusitania", which was torpedoed on 7 May 1915 during the First World War.
RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City.
 There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history.
 The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line.
 The Titanic was built by the Harland and Wolff shipyard in Belfast.
 Thomas Andrews, her architect, died in the disaster.
The American Palestine Line was a steamship company, formed in 1924 in the U.S., for the purpose of providing direct passenger service from New York to Palestine.
 It was reportedly the first steamship company owned and operated by Jews.
 The company negotiated to purchase three ocean liners from the United States Shipping Board, but it was only able to purchase one,  , a former North German Lloyd steamer that operated as "Princess Alice" before being seized by the United States during World War I.
 After refurbishing the liner, the company inaugurated service between New York and Palestine in March 1925, when "President Arthur" sailed on her maiden voyage.
 A crowd of 15,000 witnessed ceremonies that included songs, prayers, and speeches in English and Yiddish.
 The company claimed that "President Arthur" was the first ocean liner to fly the Zionist flag at sea and the first ocean liner ever to have female officers.
MS "Sagafjord was an ocean liner built in 1965 by Société Nouvelle des Forges et Chantiers de la Méditerranée for Norwegian America Line as the combined ocean liner/cruise ship.
 Between 1983 and 1996 the "Sagafjord" was operated by Cunard Line.
 In 1996—1997 she was briefly operated by Transocean Tours as MS "Gripsholm prior to being sold to Saga.
 She was lastly owned and operated by Saga Cruises on worldwide cruises targeted at the senior market out of the United Kingdom, known as the MS "Saga Rose" .
 She was retired from service in October 2009.
MS "Augustus" was a 27,090 GRT, luxurious ocean liner built in 1950 for Italian Line.
 She was the sister ship to MS "Giulio Cesare" that was launched in the same year.
 These two ships were built to the same design, with similar specifications.
 After the "Augustus" was sold to Hong Kong, she sailed under five names.
 The ship was later sold to Manila Hotel and renamed MS "Philippines", functioning as a static hotel.
 As reported by both Maritimematters, and ssmaritime, the MS Philippines, was sold for scrap in September 2011.
 As of December 2011, she was beached in Alang for scrapping.
Piero Calamai (25 December 1897 – 7 April 1972) was the Italian captain of the SS "Andrea Doria" when it sank in July 1956 after colliding with the MS "Stockholm".
Escal'Atlantic, is a museum that explores the historic ocean liner experience in Saint-Nazaire, France.
 The museum is found inside the former German World War II submarine pen in the harbour of the city port.
 It tells the history of the ocean liner, allowing the visitor to wander the insides of an “ocean liner” from the past by visiting areas of a vessel and by means of artefacts.
SS "Andrea Doria", ] , was an ocean liner for the Italian Line (Società di navigazione Italia) home ported in Genoa, Italy, most famous for her sinking in 1956, when 46 people were killed.

The RMMV (Royal Mail Motor Vessel) Oceanic was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line.
 The ship was to have been the first 1000 ft -long ocean liner.
 It was intended to be the largest ocean liner for the White Star Line, thus it would have been larger than the earlier White Star giants, "Olympic", "Titanic", "Britannic", and "Majestic".
