The Southern New Mexico State Fair, held west of Las Cruces, NM, in Dona Ana County, is an annual affair that still promotes traditional agriculture. Boasting one of the largest Junior Livestock Shows in the state, the fair invites youth from 6 counties in New Mexico and Texas to participate.

The event is generally held the first week in October, however New Mexico State Fair dates will sometimes affect the dates, causing them to be moved forward or backward one week.
