William Kenneth Warrender (August 5, 1908 – April 6, 1997) was a Canadian politician, who represented Hamilton Centre in the Legislative Assembly of Ontario from 1951 to 1962 as a Progressive Conservative member.
After winning an acclamation to City Council in 1945, Warrender served four terms as Ward Two's alderman before being elected to Hamilton's Board of Control in 1949.
In his first term, he served on as many as five Standing Committees of the Legislative Assembly simultaneously, until being appointed as the Minister of Planning and Development on January 20, 1953.
Warrender was involved in many local institutions following his retirement from politics, such as aiding in the founding of the Royal Botanical Gardens.
[citation needed] In recognition of his public service, Warrender was awarded an Honorary Doctor of Laws degree from McMaster University in 1962.
