Harold Joseph Connolly (8 September 1901 – 17 May 1980) was a Canadian journalist, newspaper editor, and politician who served as the 15th premier of Nova Scotia in 1954.
As a newspaperman, he worked for the Halifax Chronicle before serving as editor of the Daily Star.
He stood for the full-time job in the 1954 leadership convention, but was defeated by Henry Hicks when Protestant delegates formed a united front to prevent the election of Connolly, a Catholic.
The move caused a severe religious split within the party, which contributed to its defeat two years later at the hands of Robert Stanfield's Progressive Conservatives.
Connolly retired from provincial politics in 1955 when he was elevated to the Senate of Canada for the Halifax North, Nova Scotia division on 28 July 1955 following nomination by Prime Minister Louis St. Laurent.
