Margaret Pollock McPhun (8 July 1876 – 1960) was a Scottish suffragette from Glasgow who served two months in Holloway Prison in London and composed a poem about imprisoned activist Janie Allan.

[3] The sisters had both attended the University of Glasgow, where Margaret had studied psychology and obtained an MA in 1897.

[4] When they were released from Holloway Prison after two months, they were given hunger strike medals 'for Valour' by the WSPU to record their hunger strikes,[5] though the sisters had agreed that they would choose to drink from a cup to avoid being force fed through a nasal tube.

Margaret composed a poem about a fellow prisoner named Janie Allan who enjoyed popular support in Scotland.

The poem was titled "To A Fellow Prisoner (Miss Janie Allan)", and it was included in the poetry anthology Holloway Jingles published by the Glasgow branch of the WSPU later that year.
