The Liberal Democratic Federation of Hong Kong (Chinese: 香港自由民主聯會, abbreviated 自民聯; LDF) was a pro-Beijing pro-business and conservative political party in Hong Kong.

Chaired by Hu Fa-kuang and vice-chaired by Maria Tam and Philip Kwok, the leading figures included Tso Wung-wai, Howard Young, and Daniel Heung.

The party was established by a group of conservative businesspeople and professionals in the Hong Kong Basic Law Consultative Committee (BLCC), Hong Kong Basic Law Drafting Committee (BLDC), which was often called the "Group of 89", and appointed members in the Legislative Council of Hong Kong (LegCo) who worried about welfare spending and adversarial on 6 November 1990, as the reaction to the liberals forming the United Democrats of Hong Kong (UDHK) on the eve of the first direct LegCo elections.

The objective of party was to support candidates to fun in the upcoming elections.

Due to lack of popular basis and experience, the group invited Maria Tam Wai-chu, member of the Executive and Legislative Councils and her Progressive Hong Kong Society (PHKS) to join, as well as four councillors from the Hong Kong Civic Association.
