Saidie Patterson MBE (25 November 1906 – 16 January 1985) was a feminist, trade unionist and peace activist in Northern Ireland.

Saidie received a general education at Woodvale National School but was frequently absent as she was needed at home to assist with childcare.

[3] Despite many local men opposing female union activism, Patterson garnered the support of two powerful union members: an Englishman, Ernest Bevin and Belfast's Bob Getgood Patterson pushed for a female membership of one-hundred per cent of the workforce, and for support from male members.

[4] As a result of the strike, they achieved better working conditions, and a thirty-three per cent pay rise, in addition to paid holidays.

[5] Patterson began working full time as head of the textile branch of the Transport and General Workers' Union, where she had a special responsibility for women, a position she was to hold for twenty years.

[5] Patterson became a member of the Standing Conference of Women's Organisations where she worked tirelessly for the improved welfare of the female workforce.

Clement Attlee and the Labour Party swept to power with a huge majority in the 1945 General Election, and when Northern Ireland's Prime Minister called an election Patterson campaigned hard for the Northern Ireland Labour Party where she saw four candidates returned to Stormont, including her comrade Bob Getgood in the Oldpark constituency.

She delivered an oration on peace at St Patrick's Cathedral, Dublin on the occasion of the papal visit to Ireland in 1979.

[10] She was also an active member of the Girls Club Union for fifty years, where she organised classes and short breaks for underprivileged women and children.

[15] Patterson is commemorated with a blue plaque on the Shankill Road Methodist Church in Belfast, unveiled by the Ulster History Circle on International Women's Day 2018.
