Frank Wilson Parker (October 16, 1860 – August 3, 1932) was an American judge who served on the New Mexico Supreme Court for 35 years, from its territorial period to after statehood.

[4][5] He was reappointed to the Territorial Supreme Court by President Theodore Roosevelt in 1901 and 1905, and by William Howard Taft in 1909.

[1][6] While serving as a territorial district court judge,[7] he presided over two trials that received national publicity.

In 1899, ranchers Oliver Lee and Jim Gilliland were charged with the murder of lawyer and Republican politician Albert J. Fountain and his son, three years after their disappearance.

[9] In 1923, the New Mexico State Tribune, a pro-Democratic newspaper, suggested that Parker had misused court funds.
