Act of Faith is the fourth studio album by the American band Mucky Pup. It was released in 1992.
It was the last studio album to feature founding member and guitarist Dan Nastasi. It features the debuts of bassist Christopher "Junior" LaPlante and keyboardist Kevin Powers. A video was shot for the song "Mr. Hand."
The Toronto Star noted that the band "gnaw away at hardcore, power pop and the heavier end of psychedelia and don't shy from tossing samples and snatches from instruments other than the basic guitars, bass and drums into the mix."
