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

Butterfly Estate Public Library sits on the ground floor of Tip Chui House within the Butterfly Estate residential complex in Tuen Mun District. It offers collections for children, teenagers, and adults, along with computer workstations, self-checkout systems, and access to newspapers, magazines, and online resources.

The library opened on 21 May 1986 in units 126–130 on the ground floor of Tip Ying House, Butterfly Estate, with a floor area of 285 square metres; its name was approved by the Tuen Mun District Committee of the Provisional Regional Council on 27 November 1985. In December 2008 the district facilities committee allocated HK$3.6 million for relocation, raised to HK$4.2 million in June 2009 to cover larger air-conditioning and ventilation equipment and new activity and multimedia rooms. The new premises in units 123–130 of Tip Chui House opened on 11 June 2010, the same day the old library closed.

The library's name comes from Butterfly Estate, the public housing complex where it has served residents of Butterfly Estate, Wu King Estate, Siu Shan Court and the Tuen Mun Ferry Pier area since 1986. It moved from Tip Ying House to larger premises in Tip Chui House in 2010, gaining a newspaper reading room, a extension activities room and a multimedia workstation.

The library is easy to access since it sits on the ground floor of a residential building where visitors can enter conveniently. Computer workstations and self-checkout systems allow people to work and borrow materials independently, giving them flexibility to manage their time.

The library opened on 21 May 1986 in Tip Ying House, covering 285 square metres. In 2008 the Tuen Mun District Council set aside HK$3.6 million for a move, and in June 2009 the Leisure and Cultural Services Department asked for HK$4.2 million because the new premises needed large air-conditioning and return-air equipment plus a extension activity room and multimedia workstation. The new Tip Chui House site, 464 square metres, opened on 11 June 2010, the same day the old one closed.
