Lytle Creek, California, is an approximately 18-mile-long (29 km)stream in southwestern San Bernardino County near the city of San Bernardino. It is a tributary of Warm Creek, a tributary of the Santa Ana River. The Mormon settlers of San Bernardino named the stream "Lytle Creek" after their leader, Captain Andrew Lytle.

Lytle Creek flows through the eastern San Gabriel Mountains and has three forks, the North, Middle and South forks. The source of the creek is at the confluence of the North Fork and Middle Fork Lytle Creek, just west of the town of Lytle Creek, California 34°14′24″N 117°29′55″W / 34.24000°N 117.49861°W / 34.24000; -117.49861.
