Henry Shafto Harrison (1810 – 3 July 1892) was a 19th-century Member of Parliament in what was then called Wanganui, New Zealand.
Harrison was from Yorkshire, and after graduating from Cambridge came to New Zealand with wife and surviving children on the Bolton in 1840.
Because of local unrest, they moved to a farm near Fordell, which they named "Warrengate" after their Yorkshire heritage.
He won the ensuing 1861 by-election, and held it to the end of the term of the 3rd New Zealand Parliament in 1866.
John Bryce won the seat in the 1866 general election, but resigned in 1867.
