Patrick Power (March 17, 1815 – February 23, 1881) was a Canadian politician and a Member of Parliament for the riding of Halifax in Nova Scotia.

In 1876, he was offered a position in Alexander Mackenzie's Cabinet to replace Thomas Coffin, but he declined.

During life, he worked on various boards and commissions themed with the education and welfare of the poor.

For his charity work, he was awarded the Order of St. Gregory the Great by Pope Pius IX in 1870.

The Patrick Power Library at St. Mary's University in Halifax bears his namesake.
