Lone Star Derby

The Lone Star Derby is an American flat Thoroughbred horse race for three-year-olds held annually at Lone Star Park in Grand Prairie, Texas. It is currently an Ungraded stakes race run over a distance of 8.5 furlongs on turf.

Inaugurated in 1997 as an ungraded stakes race, it was elevated to Grade III status in 2002. The race was downgraded by the American Graded Stakes Committee (AGSC) and lost its graded status in 2011. Lone Star Park officials moved the race from dirt to turf for the first time after the AGSC decision and moved it to Lone Star Park's special Memorial Day program dubbed Lone Star Million Day.

For the three years from 2001 through 2003, it was raced at $1 1/16$ miles.
