HMS Cornflower (Chinese: 禾花) was an Arabis-class sloop of the Royal Navy and from 1933 the Hong Kong Naval Volunteer Force (HKNVR).

[4][a] They were designed at the start of the First World War as relatively fast minesweepers that could also carry out various miscellaneous duties in support of the fleet such as acting as dispatch vessels or carrying out towing operations, but as the war continued and the threat from German submarines grew, became increasingly involved in anti-submarine duties.

[10] The ship was built by the Scottish shipbuilder Barclay, Curle and Company at their Whiteinch, Glasgow shipyard as yard number 537,[11] was launched on 30 March 1916,[7] and completed on 4 May that year.

A river steamer, SS Tai Hing, began to receive refitting in March 1940 to replace Cornflower as the headquarters of the HKNVR.

Tai Hing was renamed Cornflower after her predecessor to strengthen the unit's identify and esprit de corps.
