Haddon Township is a township in Camden County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 15,407, an increase of 700 (+4.8%) from the 2010 census count of 14,707, which in turn reflected an increase of 56 (+0.4%) from the 14,651 counted in the 2000 census.
 Under the terms of an act of the New Jersey Legislature on February 23, 1865, Haddon Township was incorporated from portions of Newton Township. The following communities were subsequently created from the Haddon Township: Haddonfield (April 6, 1875), Collingswood (May 22, 1888), Woodlynne (March 19, 1901), Haddon Heights (March 2, 1904), Audubon (March 13, 1905) and Oaklyn (also March 13, 1905). The township was named for early settler Elizabeth Haddon.
 Haddon Township allows the sale of alcohol, and has several bars and restaurants which serve alcoholic beverages, unlike the neighboring boroughs of Collingswood, Haddonfield and Haddon Heights which prohibit the sale of alcohol.
 The township's first European settlers settled in the area of Newton Creek in 1681. In 1701, Elizabeth Haddon Estaugh, the daughter of John Haddon, arrived in the American colonies to oversee his large landholdings, which included areas that are now Collingswood, Haddon Township, and Haddonfield. Contemporary Newton Township included land that later became part of Audubon, Audubon Park, Camden, Collingswood, Gloucester City, Haddon Heights, Haddonfield, Oaklyn, and Woodlynne.
 In the late 1830s, a runaway enslaved man, who had taken the surname Saddler to avoid detection by his former master, came to New Jersey from a Maryland plantation with his wife and two daughters. Saddler worked for Cy Evans, a local Quaker farmer, from whom he bought five acres to farm.  The area where Saddler settled became a predominantly black community known as Saddlertown, a stop on the Underground Railroad. Today, Saddlertown is racially diverse.
 According to the United States Census Bureau, Haddon Township had a total area of 2.82 square miles (7.30 km2), including 2.69 square miles (6.97 km2) of land and 0.13 square miles (0.33 km2) of water (4.54%).
 Haddon Township has two exclaves, West Collingswood Heights and West Collingswood Extension. The downtown portion of the township is known as Westmont, a name probably derived from a noted harness racing horse. Other unincorporated communities, localities and place names located partially or completely within the township include Crystal Lake, Cuthbert and Oakdale.
 Haddon Township borders the Camden County municipalities of Audubon, Audubon Park, Camden, Cherry Hill (water border), Collingswood, Gloucester City, Haddonfield, Mount Ephraim, and Oaklyn.

 Since 1950, Haddon Township has been governed under the Walsh Act with a governing body comprised of a three-member commission. The Township is one of 30 municipalities (of the 564) statewide governed under the commission form of government. Commission members are elected at-large on a non-partisan basis as part of the May municipal election to serve four-year concurrent terms of office. At a reorganization meeting held after the election, each commissioner is assigned responsibility for supervising a specific department. The commissioners select one of their members to serve as a part-time mayor, who presides over meetings but has no independent executive function. Haddon Township has had only three mayors in its history: William Rohrer, William J. Park. Jr., (1997 New Jersey State League of Municipalities Mayors Hall of Fame), and Randall Teague.
 As of 2023, members of the Haddon Township Commission are 
Mayor Randall W. "Randy" Teague (Commissioner of Public Works, Parks and Public Property), 
Ryan Linhart (Commissioner of Revenue and Finance) and 
Jim Mulroy (Commissioner of Public Affairs and Public Safety); all serving terms of office that end May 16, 2027. Linhart, Mulroy and Teague ran unopposed in the May 2023 municipal election, the fourth consecutive time that township candidates won election to four-year terms, without facing any challengers.
 In November 2018, Ryan Linhart was appointed to fill the seat vacated by Paul Dougherty, who resigned the previous month before he pleaded guilty to a criminal charge.
 Jim Mulroy was sworn into office in February 2017 to fill the seat vacated by John Foley, who resigned from office earlier that month.
 Haddon Township has three fire districts (a fourth, District 2, was dissolved in 2016), each governed by five elected fire commissioners. Fire District 1 is the Westmont and Bluebird section, protected by the Westmont Fire Company No. 1, which was established in 1902. The former Fire District 2 covered the West Collingswood Extension section. Since being dissolved, Haddon Township now contracts directly with the Borough of Collingswood Fire Department (Station 16-1) for fire protection in the Extension section. Fire District 3 is the Bettlewood, Heather Glen, Heather House and Heather Woods sections and it contracts with the Westmont Fire Company No. 1 for fire protection from District 1.  Fire District 4 is the West Collingswood Heights section, protected by the West Collingswood Heights Fire Co.  Westmont Fire Co. (Station 15-1) and West Collingswood Heights Fire Co. (Station 15-2) are both Haddon Township companies, but separate entities with their own chiefs.
 Ambulance service throughout the Township is also divided, mirroring the fire service.
 The Westmont Fire Company No. 1 provides both fire and EMS services.  John D. Medes has served as Chief since 2007.
