St Brigid's was a Roman Catholic church located in the Lower Town neighbourhood of Ottawa, Ontario, Canada.

Until the opening of St Brigid's, this community, largely of Irish heritage, had formed part of the parish of Notre-Dame, the Cathedral of Ottawa.

[1] Built in the Romanesque Revival style (generally called Norman at that time), the principal façade has three heavy round headed portals and paired towers of unequal height and detail.

In May 2006, Archbishop Marcel Gervais announced that the church would be closed, as the shrinking congregation did not justify the several hundred thousand dollars in needed repairs.

The church was purchased by a numbered company owned by former congregation member Patrick McDonald, a Portarlington, Count Laois-born man who moved to Canada in 1989.

[7] On September 23, 2022, the Ontario Superior Court of Justice ruled that TUPOC had materially breached the sale agreement by failing to make required payments despite two extensions, granted the eviction application, and awarded $53,000 in damages to the owners.
