The Trilobite Wilderness is a wilderness area in the Marble Mountains of the eastern Mojave Desert in northeastern San Bernardino County, California. It is named for the large number of trilobite fossils that can be found within its boundaries. Aside from its paleontological significance, it is home to typical flora and fauna of the Mojave Desert, including a stable population of bighorn sheep and desert tortoise. The area was created as an addition to the National Wilderness Preservation System in 1994 as a part of the California Desert Protection Act.

The site is managed by the Bureau of Land Management. It is one of six wilderness areas in Mojave Trails National Monument, established in 2016.
