The Southwestern Region of the NSS is a Region of the National Speleological Society, and was founded in 1962. The Southwestern Region spans New Mexico, west Texas, and eastern Arizona. These boundaries overlap boundaries recognized by the Texas Speleological Association and The Arizona Regional Association.

Regional activities include exploration, mapping, cave inventory, scientific study, public education and awareness, and conservation and restoration volunteer efforts with the NPS, BLM, and USFS. The Southwestern Region holds four Regional meetings a year. Three of them are field meetings, and include caving activities and/or volunteer projects. The Winter Technical is held indoors with technical papers presented.

Regular membership is ten dollars per year, and includes six issues of the Southwestern Cavers newsletter. Additional family members (living at the same address) are an additional one dollar each, but do not receive the newsletter. The individual members (regular or family) present at a Regional meeting are the voting members of the Region; member grottos have no voting franchise. Subscriptions are available without membership for nine dollars per year.
