Michael Patrick Ryan (September 29, 1825 – January 18, 1893) was an Irish-born Canadian businessman and political figure.

[2] He was born in Pallis, Donohill, County Tipperary, in Ireland in 1825,[2] the son of William Ryan,[1] and came to Lower Canada with his family in 1840, settling near Chambly.

Following the assassination of Liberal-Conservative Member of Parliament Thomas D'Arcy McGee in April 1868, Ryan was selected by the party to run in the ensuing by-election.

Due to the circumstances of the by-election Ryan's candidacy was unopposed and he was elected to the House of Commons by acclamation.

[3] In 1882, he was named customs collector at Montreal[4] and served in that post until his death in January 1893.
