Tseung Kwan O Public Library, Public library in Sai Kung District, Hong Kong.

Tseung Kwan O Public Library is a two-storey public library at 9 Wan Lung Road, Po Lam, in Sai Kung District, Hong Kong. Its exterior was modelled on a spaceship and has also been described as a covered Roman amphitheatre. The ground floor holds the students' study room, children's library and activity room; the first floor holds the adult library, newspaper reading room, multimedia library, computer information centre and reference section.

The library was built to serve Tseung Kwan O, one of Hong Kong's newer planned residential towns, as the population of the area grew. It became part of the city's public library network when housing development in this part of Sai Kung District expanded.

The library opened on 21 July 2001 with about 180,000 items: 150,000 Chinese and English books, some 7,000 reference volumes, around 9,000 audiovisual items such as CDs and cassettes, and 160 newspaper and magazine titles. About 45,000 of the books were children's titles. It was the first Hong Kong public library with self-service borrowing machines.

The library is close to Po Lam MTR Station, making it easy to reach by public transport from most parts of the city. Opening hours on weekdays and weekends may differ, so it is worth checking ahead of your visit.

The library was the first in Hong Kong to have its own standalone building and the first public library in the city to install self-service borrowing machines. Its roof uses a glass curtain wall to bring natural light into the reading areas.
