John Tracy Morrison was the sixth Governor of Idaho from 1903 until 1905.

In 1891, Morrison was influential in founding the College of Idaho and served as an original faculty member, teaching English and history. In 1893 he became a member of the school’s board of trustees. He served on the board of trustees until 1904.

An unsuccessful candidate for state legislature in 1896, Morrison was Chairman of the Republican State Central Committee from 1897 to 1900.

Idaho Republicans nominated Morrison as their gubernatorial candidate in 1902. He was elected by defeating the Democratic incumbent, Frank W. Hunt. During his term in office, state examinations of weights and measures were initiated, a pure food law was enacted, and a reform school at St. Anthony was founded.

Morrison sought reelection in 1904, but Republicans declined to nominate him for a second term, instead supporting Frank R. Gooding. Upon leaving office on January 2, 1905, he returned Caldwell, and resumed his law practice.
