Patrick "Pat" Bagley (born 1956) is a liberal American editorial cartoonist and journalist for The Salt Lake Tribune in Salt Lake City, Utah, and an author and illustrator of several books.
Bagley was born in Salt Lake City and raised in Oceanside, California, where his father was mayor and his mother was a school teacher. Always interested in politics, during high school Bagley participated in a PBS interview of Ronald Reagan. As a member of The Church of Jesus Christ of Latter-day Saints (LDS Church), he was a proselyting missionary in the Bolivia La Paz Mission from 1975–77. In 1978 he received his degree in political science, with a history minor, from Brigham Young University (BYU) in Provo, Utah.
Bagley has two sons, Miles and Alec. Will Bagley, Pat's older brother, is an accomplished historian of the western United States and coauthored This is the Place!: A Crossroads of Utah's Past with Pat in 1996.
In October 2009, while reacting to recent statements by Dallin H. Oaks, an LDS Apostle, about gay marriage protesters and religious freedom, Bagley commented that he was "retired" from the church, though not bitter or angry, and considers his LDS life a "good experience" and "in my blood."
