Ophioglossales (lit. 'snake-tongue [plants]') are a small group of pteridophyte plants. Traditionally they are included in the division Pteridophyta, the ferns, originally as a family and later as the order Ophioglossales. In some classifications this group is placed in a separate division, the Ophioglossophyta, but recent molecular systematic studies have shown the Ophioglossales to be closely related to the Psilotales. The most recent classification by Smith et al. (2006) places these two orders together in class Psilotopsida.
