Johnson Creek is a stream in the Trinity River watershed in North Texas (USA).
The creek rises near Interstate 20 in eastern Tarrant County and runs northeasterly for 13 miles (21 km) to the West Fork of the Trinity River in Grand Prairie, within Dallas County. The creek flows through the cities of Arlington (including through the Six Flags Over Texas amusement park) and Grand Prairie and is generally completely bounded by development. In areas where development has not been substantial, native honeysuckle (Lonicera spp.), trumpet creeper (Campsis radicans), mustang grape (Vitis mustangensis), American Elm (Ulmus americana), hackberry (Celtis laevigata), oak (Quercus spp.), pecan (Carya illinoinensis), and eastern cottonwood (Populus deltoides) can be found growing along the banks.
The creek is likely named after Middleton Tate Johnson who settled in the area in the early 1840s.
