Tuen Mun Public Library, Public library in Tuen Mun District, Hong Kong.

Tuen Mun Public Library occupies a 3,250-square-metre floor area at 1 Tuen Hi Road in Tuen Mun town centre, making it Hong Kong's seventh-largest public library by area. It opened in 1989 on land reclaimed from Castle Peak Bay. Its floors hold an adult lending library, a children's library, a reference library, a multimedia library, a newspaper reading room, a computer information centre, a coffee corner and a students' study room.

The library opened on 19 December 1989 as Tuen Mun Central Library, built by the Regional Council on reclaimed land at Castle Peak Bay. After the council was dissolved in 2000, the Leisure and Cultural Services Department took over its management. It was renamed Tuen Mun Public Library in 2001 to avoid confusion with the Hong Kong Central Library.

The library's name changed from Tuen Mun Central Library to Tuen Mun Public Library in 2001, when the new Hong Kong Central Library opened and the two names risked confusion. The building stands on reclaimed land at Castle Peak Bay, and part of its podium houses the Tuen Mun Central Post Office.
