Helen Kirkpatrick Watts (1881 – 18 August 1972) was a militant British suffragette from Nottingham.

[1][2] Her father, Alan Hunter Watts, was the vicar at Holy Trinity Church in Lenton near Nottingham; her mother was Ethelinda Woodrow Cassels.

She came to notice after she joined the Women's Social and Political Union in 1907 after being inspired by a local speech by Christabel Pankhurst.

Emily Blathwayt had chosen a field in the grounds of their house where suffragettes who had been imprisoned were celebrated with a particular conifer.

[7] Like the Blathwayts, Watts did not agree when the WSPU hardened its militancy to include acts of arson.

[6] On 22 November 2018–100 years to the day after women were first able to vote in a general election—a juniper tree was planted in Watts' honor at the Arboretum Park in Nottingham.
