Margaret Duchill (died 1658) was a Scottish woman who confessed to witchcraft at Alloa during the year 1658.

[2] The Alloa witch hunt began when the presbytery of Stirling met and appointed the Reverends Matthias Symson (1625–1664) and George Bennet, to visit the town and investigate a group of suspected witches.

In turn at her trial on 22 June 1658 she implicated Katherine Remy and Margaret Talzeor.

[4] There were a total of 12 women accused of witchcraft from the urban parish, which may include Alloa's adjacent rural area.

[6] Her trial testimony involved mentions of demons, fairies and elements of maleficium.
