Harriet Russell Morison (1862 – 19 August 1925) was a New Zealand tailor, trade unionist, suffragist and public servant.

[3][4] Morison also campaigned for women's suffrage, which she considered a natural part of egalitarian Christian principles.

Part of her job was to raise funds for the union, but two picnics she organised in 1895 were unsuccessful due to the weather, and for a carnival in 1896 she failed to keep proper books.

The New Zealand Herald obituary describes her as having "a keen personal interest in the welfare of the mentally afflicted".

[6] Morison is one of six figures honoured in the Kate Sheppard National Memorial in Christchurch, which was unveiled in 1993 on the 100th anniversary of suffrage in New Zealand.
