Katharine "Kate" Parry Frye (née Collins; 9 January 1878 – 16 February 1959) was a British actress, a lifelong diarist and suffragist.

[2] In 1902 she attended the Shakespearean actor Ben Greet's Acting Academy where she learnt about the stage.

[2] She joined the London Society for Women's Suffrage and the Actresses' Franchise League.

Katharine's diary records the changes that became essential given her lack of money and she blamed her father for their misfortune.

Frye's diary gave a report of the Emily Wilding Davison's funeral noting the matching outfits and the special pallbearers.

[2] In the 1930 Frye returned briefly to acting when she appeared in a walk on part under her stage name of Katherine Parry.

Her writing was heard later during the second world war when their amateur productions in their garden theatre at Berghers Hill in Buckinghamshire raised funds for charity.
