Aden Lava Flow Wilderness, Nature reserve in Doña Ana County, United States.

Aden Lava Flow Wilderness is a 25,287-acre Bureau of Land Management wilderness in the Potrillo volcanic field southwest of Las Cruces, New Mexico. It lies south of County Road B002, with Aden Crater at the western side of the lava flow. The protected area is part of the Organ Mountains-Desert Peaks National Monument.

The area gained official protection through the John D. Dingell Jr. Conservation Act in 2019, making it part of the national wilderness system. This designation formally preserved the volcanic landscape for long-term conservation.

The wilderness lies within the Potrillo volcanic field, and Aden Crater sits at the western edge of the lava flow. The flow is part of the Organ Mountains-Desert Peaks National Monument, alongside neighbouring Broad Canyon and Cinder Cone Wildernesses. Visitors cross open basalt on foot; there are no trails or facilities.

The reserve is reachable from Las Cruces by traveling west on Interstate 10, then following local roads to the entrance area. Visitors should stay on marked routes and prepare for varying desert terrain and weather conditions.

Aden Crater sits at the western edge of the lava flow, and the flow lies within the Potrillo volcanic field southwest of Las Cruces. Before 2019 the land was a BLM Wilderness Study Area, and the Dingell Act then folded it into the National Wilderness Preservation System.
