Catherine Anne Fox (18 May 1877 – 23 October 1915) was a New Zealand nurse who served in the First World War and died when the SS Marquette was torpedoed and sunk in 1915.

In July 1915, Fox enlisted in the New Zealand Army Nursing Service and left Wellington on board the SS Maheno.

The ship sailed to Port Said, Egypt, and the contingent of nurses worked in a stationary hospital there.

A commemorative plaque to Fox, and fellow Marquette casualties Mary Gorman and Isabel Clark, was placed in Waimate Hospital.

[4] Fox is named on the Mikra British Cemetery in Greece and in the Nurses' Memorial Chapel at Christchurch Hospital.
