Peter Michael Liba CM OM (May 10, 1940 – June 21, 2007) was a Canadian journalist, businessman and 22nd Lieutenant Governor of Manitoba.
Liba was born in Winnipeg, and began his journalistic career working for the Portage la Prairie Daily Telegraph and the Neepawa Press.
In 1984 Liba was appointed a member of the Order of Canada and in 1998 was inducted into the Canadian Association of Broadcasters Hall of Fame.
The appointment as Manitoba's lieutenant-governor may have been, in part, a reflection of Canadian prime minister Jean Chrétien's friendship with Israel Asper.
Liba was made the first member of the Order of Manitoba in 1999, and received the Queen Elizabeth II's Golden Jubilee Medal in 2004.
