Brigid Makowski (née Sheils; 6 January 1937–15 April 2017) was an Irish Republican activist and politician from Derry, Northern Ireland.

During the Irish War of Independence, Paddy Shiels was jailed again and subsequently went on hunger strike in protest.

She would also begin attending the Republican Clubs, a front for Sinn Féin which had been banned in Northern Ireland since 1964.

In August 1969 she was present for the Battle of the Bogside; Makowski (pregnant with her fifth child at the time) and her sister provided medical aid to Catholics from their mother's apartment.

In July 1970 Makowski was a part of a sit-in protest against the British Consulate in Philadelphia following the Falls Curfew.

There, Makowski formally joined Official Sinn Féin, siding with the Marxist-oriented group over the "traditional republicans" in the Provisional camp.

In January 1972 Makowski was arrested and jailed for collecting funds (for Official Sinn Féin) without a permit.

Months later, Makowski was charged with non-payment of a fine, membership of the Irish Republican Army, and incitement to violence.

[7] In 1972 Makowski disagreed with the decision by the Official IRA to participate in a ceasefire and thereafter became a supporter of Seamus Costello.

[citation needed] In 1992, she was present at the funeral of the Irish People's Liberation Organisation and Republican Socialist Collective leader Jimmy Brown.
