Flight Lieutenant Thomas Grey Culling DSC (31 May 1896 – 8 June 1917) was New Zealand's first flying ace of the First World War.

Born in Dunedin, New Zealand, Culling joined the Samoa Expeditionary Force following the outbreak of the First World War but was prevented from departing the country by his father, due to his age.

He shot down his first German aircraft in April 1917 and would be credited with a total of six aerial victories, the first New Zealander to become a flying ace during the war, by the time of his death on 8 June 1917.

His grandfather, also Thomas Culling, was a printer and paper mill director, and was one of Dunedin's early colonial settlers, arriving in the city just one year after its 1848 founding.

[2] The following year, in August, Culling left New Zealand for England to join the Royal Naval Air Service.

The medal was presented by the Earl of Liverpool, Governor-General of New Zealand, to his father in a ceremony at Auckland the following year.
