The Progress Singapore Party (abbreviation: PSP) is a liberal political party in Singapore. It was one of the three political parties represented in the 14th Parliament, alongside the governing People's Action Party (PAP) and the fellow opposition Workers' Party (WP); Leong Mun Wai and Hazel Poa represented it as non-constituency Members of Parliament (NCMPs).

The PSP was founded in 2019 by 11 members, including former PAP politician Tan Cheng Bock, allegedly to address PAP leadership decisions; Lee Hsien Yang, the estranged brother of then-Prime Minister Lee Hsien Loong, supported it. It held multiple talks and walkabouts throughout 2019, ahead of the 2020 general election, where it contested in nine constituencies. While defeated in all nine constituencies, the party became eligible for two NCMP seats, which Leong and Poa accepted. The two had been part of the PSP team for West Coast Group Representation Constituency (GRC), which garnered 48.32% of the vote.

In the 2025 general election, the PSP contested in six constituencies and faced a significant decline in support. It garnered 4.88% of the nationwide popular vote, and was not offered NCMP seats.
