Nigel Ian Pengelly (May 29, 1925 – July 3, 2010) was a provincial level politician from Alberta, Canada. He served as a member of the Legislative Assembly of Alberta from 1979 to 1989. He sat in the back benches of the governing Progressive Conservative caucus.
Pengelly ran for a seat to the Alberta Legislative Assembly in the 1979 Alberta general election. He won the Innisfail electoral district by a wide margin defeating three other candidates to hold it for the governing Progressive Conservative caucus. He would be re-elected to a second term with his largest plurality in the 1982 Alberta general election. The general election of 1986 Alberta general election would see Pengelly re-elected to his third and final term. His popular vote dropped significantly but he still won with a landslide margin. Pengelly would not run for another term and retired from provincial politics at the dissolution of the Assembly in 1989.
