Lizzie Frost Rattray (née Fenton, 22 March 1855 – 12 August 1931) was a New Zealand journalist, suffragist and welfare worker.

Rattray was born on 22 March 1855 in Dunedin, Otago, New Zealand to Mary Lister and Archdeacon John Albert Fenton.

After their return to New Zealand Lizzie married William Rattray a prosperous Auckland draper.

After initial interest in charity work for the St John Ambulance, Lizzie moved on to suffrage and other feminist causes, using her position as a journalist to get her message heard.
