Brian Anthony Brennan (born October 4, 1943) is a Canadian journalist, broadcaster, musician, and writer who specializes in books about the colourful personalities of Western Canada's past.
Born in Dublin, Ireland, he immigrated to Canada in 1966 and has lived in Calgary, Alberta since 1974. He spent 25 years as a staff writer with the Calgary Herald, writing columns and feature stories.
Brennan was a leader in the attempt by the Communications, Energy and Paperworkers Union of Canada to organize a union local and negotiate a first contract with the Calgary Herald. Before and during the eight-month strike by journalists in 1999 and 2000, Brennan was a member of the union's bargaining committee. When the strike ended in June 2000 with the dissolution of the union, he left to devote himself full-time to writing books and magazine articles.
As a storyteller, Brennan has been heard frequently on the CBC Radio program Daybreak Alberta.
Brennan was short-listed for the 2003 Grant MacEwan Author's Award, nominated for the Irish Times Literature Prize, 2001, and has received two Western Magazine Awards and the national Hollobon Award for journalism. He was the first winner of the Dave Greber Freelance Writers Award, presented in 2004.
