Adrian Tan Cheng Bock (born 26 April 1940) is a Singaporean former politician and physician who was the secretary-general of the Progress Singapore Party (PSP) between 2019 and 2021 and its chairperson between 2021 and 2025.

As a member of the governing People's Action Party (PAP), he was the Member of Parliament (MP) for Ayer Rajah Single Member Constituency (SMC) between 1980 and 2006. He left politics before the 2006 general election and later left the PAP to contest the 2011 presidential election, losing marginally with 34.85% of the vote to Tony Tan in a four-cornered fight.

Tan founded the PSP in 2019. It did not win any seats in the 2020 or 2025 general elections, but was awarded two non-constituency MP seats in 2020 after its team for West Coast Group Representation Constituency (GRC), led by Tan himself, won 48.31% of the vote, the closest result in the general election. He announced his retirement from politics shortly after the 2025 general election, but has remained a PSP member.
