Martina Anderson (born 16 April 1962) is an Irish[2] former politician from Northern Ireland who served as Member of the Legislative Assembly (MLA) for Foyle from 2020 to 2021, and previously from 2007 to 2012.

[7] She has six sisters and three brothers, one of whom, Peter, is a former Sinn Féin councillor, and her niece is former Irish Senator and former Foyle MP Elisha McCallion.

[9] Anderson was arrested aged 18 leaving a furniture store in Derry and charged with possession of a firearm and causing an explosion.

She was released on bail after spending two months in Armagh Women's Prison and fled across the border to Buncrana in County Donegal.

[3][10] Anderson was again arrested on 24 June 1985 at a flat in Glasgow with four other IRA members including Brighton bomber Patrick Magee.

[16] In December 2007, Anderson said she was concerned that large numbers of migrant workers from mainly Catholic countries were being classed as 'Catholic/nationalist' in monitoring forms, rather than 'other'.

[22][23][24] In the 2019 European Parliament elections, Anderson was returned on the fifth ballot, after Diane Dodds of the Democratic Unionist Party and Naomi Long of Alliance.

After her seat was abolished due to Brexit, on 10 February 2020 she became an MLA for Foyle for a second time, after being selected by Sinn Féin to replace Raymond McCartney.
