In the United States, the 31st parallel defines part of the border between Mississippi and Louisiana, and part of the border between Alabama and Florida.

The 31st parallel north is a circle of latitude that is 31 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean.

Part of the border between Iran and Iraq is defined by the parallel. In the United States, it defines part of the border between the states of Mississippi and Louisiana, and most of the border between Alabama and Florida.

Andrew Ellicott surveyed this parallel in 1797, when it was the border between the United States and Spanish territory.

At this latitude the sun is visible for 14 hours, 10 minutes during the summer solstice and 10 hours, 8 minutes during the winter solstice.
