John McNairy (March 30, 1762 – November 12, 1837) was a U.S. federal judge in Tennessee. He was the judge for the Southwest Territory, and for the United States District Court for the District of Tennessee, the United States District Court for the Eastern District of Tennessee and the United States District Court for the Western District of Tennessee, back when one judge covered all three districts. McNairy and Andrew Jackson went to school together and read law together, and travelled together to the Mero District of North Carolina in the late 1780s to set up the federal judiciary in what is now Tennessee. George Washington appointed McNairy to be judge, and McNairy appointed Jackson to a position roughly equivalent to U.S. Attorney.
