The Prosperity for Posterity Party (PPP) was a short-lived political party in Manitoba, Canada. It was established for the 1953 provincial election, but dissolved before the election took place. The party was established by William Bayley, who had served in the Legislative Assembly of Manitoba in the 1920s as a Labour representative. Bayley was a staunch prohibitionist, and opposed 1950s efforts to liberalize Manitoba's liquor laws. He was particularly opposed to the policies of Stephen Juba, who had called for a provincial referendum on the issue.
