Oswald Smith Crocket, son of William and Marion (Caldwell) Crocket, was born 13 April 1868 at Chatham, New Brunswick of Scottish ancestry. Educated in Fredericton public schools, Oswald Crocket graduated from the University of New Brunswick with a bachelor of arts degree in 1886. He studied law and was admitted to the bar of New Brunswick as an attorney in 1891 and as a barrister in 1892. His first marriage to A. Stranger of Fredericton, contracted on 20 July 1893, produced a son Stranger. Following her death, in 1905, Crocket married Clarine Stevenson of Coaticook, Quebec, and they had two children, Gordon Oswald and Muriel Isabel.

Residing in Fredericton where he practised law, Crocket was active in the community. With other city residents, he worked to secure the construction of St. Andrew's Presbyterian Church and the Dominion Experimental Station, both at Fredericton, and he was a prominent member of the St. Andrew's Society. Appointed king's counsel, Crocket was awarded an honourary doctor of laws degree from UNB in 1914.

First elected in the House of Commons as a Conservative member for York County at the general election of 1904, Crocket was re-elected in 1908 and 1911. He sat in the Commons until December 1913, when he resigned on being appointed a justice of the Supreme Court of New Brunswick. He held that position until 1932 when he was appointed to the Supreme Court of Canada. He retired from the Supreme Court in 1943. Oswald Crocket died at Ottawa, Ontario on 2 March 1945 and is buried in Forest Hill Cemetery, Fredericton.
