The Progressive Liberal Party (abbreviated PLP) is a populist and social liberal party in the Bahamas. Founded in 1953, it was the first national political party in the Bahamas. After winning the 1967 general election, the party governed from 1967 to 1992, as well as from 2002 to 2007 and 2012 to 2017.

In September 2021, the PLP defeated the ruling FNM in a snap election and Philip Davis was sworn in as the new Prime Minister of Bahamas. Davis is the current leader of the party, as both the chairman of the party and Prime Minister and leader of the party in Parliament.

The PLP was founded in 1953 by William Cartwright, Cyril Stevenson, and Henry Milton Taylor. In 1953, Cartwright, who was the owner of The Bahamas Review and Stevenson, who was a journalist at the Nassau Guardian, travelled to London to cover the coronation of Queen Elizabeth II. While there, they met with representatives of the British Labour Party. The pair also travelled to Jamaica where they met with members of the Jamaican Labour Party and the People's National Party.

Later that year, Stevenson and Cartwright, together with Henry Milton Taylor formed the Progressive Liberal Party (PLP). It was the first national political party in the Bahamas. Taylor became chair, Cartwright the treasurer, and Stevenson secretary-general of the new party. Lynden Pindling, a newly-qualified lawyer, returned from England a few months later and joined the nascent party.

In 1956, the PLP won one third of the popular vote and six PLP MPs were elected to the House of Assembly, the lower house of parliament. The "Magnificent Six," as the group of six would be called, formed the first opposition block in parliament. The group of six consisted of Stevenson, Pindling, Randol Fawkes, Milo Butler, Sammy Isaacs, and Clarence A. Bain.

In January 1967, the predominantly white United Bahamian Party (UBP) government called a snap election. Of the 38 seats contested, the ruling UBP won 18 seats and the PLP won 18 seats. Two independents had also been elected: Randol Fawkes, leader of the Labour Party and a former member of the PLP, and Alvin Braynen. Fawkes and Braynen threw their votes behind the PLP making it the first time that the Bahamas was run by a black government (achieving what is commonly known in the Bahamas as "majority rule"). Braynen became the Speaker of the House of Assembly and Fawkes the Minister of Labour and Commerce.

Leading the party to its first victory in 1967 was Pindling, who became Premier and, after independence in 1973, the country's first Prime Minister.

The PLP would go on to govern for 25 straight years from 1967 to 1992, as well as from 2002 to 2007 and 2012 to 2017.
