Olive Wharry (29 September 1886 – 2 October 1947) was an English artist, arsonist and suffragette, who in 1913 was imprisoned with Lilian Lenton for burning down the tea pavilion at Kew Gardens.

In November 1911 Wharry was arrested for taking part in a WSPU window-smashing campaign, and, after being released on bail guaranteed by Frederick Pethick-Lawrence and Mrs Saul Solomon, was sentenced to two months' imprisonment.

In November 1912 she was reported as being arrested as "Joyce Locke" with other suffragettes, Fanny Parker and Marion Pollock in Aberdeen Music Hall, found hiding there before the Chancellor of the Exchequer was due to speak, carrying 'explosive' toy guns, and involved in a scuffle during Lloyd George's meeting.

[6][4] On 7 March 1913, aged 27, she and Lilian Lenton were sent to Holloway Prison for setting fire to the tea pavilion at Kew Gardens, causing £900 worth of damage.

During her trial at the Old Bailey Wharry was again charged under the assumed name "Joyce Locke" and regarded the proceedings as a "good joke".

[9][10] Wharry was arrested and imprisoned eight times between 1910 and 1914 for her part in various WSPU window-smashing campaigns, sometimes under the name "Phyllis North", sometimes as "Joyce Locke".

It is full of drawings of prison life, satirical poems, autographs of other suffragettes and a photograph of herself and Lilian Lenton in the dock during their trial for the arson attack on Kew Gardens of 1913.

[13] She made fellow Suffragette Constance Bryer (1870–1952) an executor of her 1946 will, in which she requested that her body be cremated and her ashes scattered on "the high open spaces of the Moor between Exeter and Whitstone".
