Clarence Dexter Wiseman, OC (June 19, 1907 – May 4, 1985) was the tenth General of The Salvation Army from 1974 to 1977.

Clarence Dexter Wiseman was born at Moretons Harbour, Colony of Newfoundland on June 19, 1907. Being the son of Salvation Army officers, he moved frequently from one home to another as his parents postings necessitated.

At the age of nineteen Clarence became a cadet at The Salvation Army’s Training College in Toronto, and was commissioned as an officer on July 4, 1927 with the rank of lieutenant. His first appointment was to Bedford Park Corps (Toronto). Six months later he was transferred to Yorkville Corps, Toronto, both appointments being as assistant to the commanding officer.

On January 29, 1932 the then Captain Wiseman was married to Captain Janet Kelly. He was then on the staff of the editorial department at Territorial Headquarters but soon after their marriage Captain and Mrs Wiseman were appointed to London South Corps and continued to work in corps appointments until mid 1940.
