Kat O (Chinese: 吉澳) also named Crooked Island, is an island in Northeast Hong Kong. Administratively, it is part of North District.

Kat O is located in the west of Mirs Bay.[1] With an area of 2.35 km²,[2] it is the largest island in North District, the second largest being Wong Wan Chau (Double Island).[3] Neighbouring islands include: Ap Chau, Ngo Mei Chau (Crescent Island), and Pak Sha Chau (Round Island). The village of Tung O (東澳) is located on its northwest coast.[3] Its highest point is Kai Kung Leng (雞公嶺), which is 122 m above sea level.[1]


Kat O was once a major fishing market in Hong Kong,[4] and long served as an important stopover for boats travelling between Hong Kong and the rest of China.[5]

During the Ming dynasty, a decree required all inhabitants to leave the island. Then in the 1660s, soon after the end of the dynasty, it was re-settled by Hakka people.[5] Other residents were Tanka fishermen.[4]

The Tin Hau Temple at Kat O was estimated to be built in 1763.[6] It is listed as a Grade III historic building.[7] Part of the temple building was used for the Tat O School until the school was moved to a new location in 1957.[4] A Pak Kung Shrine is also located in the vicinity.[8]

The island is home to three cannons. These are thought to have been made in the west, during the 19th century.[8]


Kat O was part of the Plover Cove (Extension) Country Park since 1979.[9]

The Kat O Nature Trail spans 1 km long, stretching from the Kat O Ferry Pier to Ko Tei Teng (高地頂).[1]

The Kat O Geoheritage Centre (at No. 142 Kat O Main Street) was opened in 2010[10] by Kat O villagers, volunteer groups and the government to raise public awareness of geo-conservation, as part of the Hong Kong Geopark.[11]
