Ceratozamia hildae, commonly known as the bamboo cycad, is a species of cycad in the family Zamiaceae that is endemic to Mexico. Ceratozamia hildae inhabits deciduous oak woodlands at elevations of 850–1,300 m.
Ceratozamia hildae is one of many species of Mexican cycad commercially exploited and is a prime example of a plant seriously threatened by trade. It is estimated that thousands of plants were removed from habitat and that only small and scattered subpopulations remain. Ceratozamia hildae is critically endangered and near to extinction in the wild, although abundant in cultivation. The bamboo cycad is an acaulescent fernlike perennial plant. It is unique among cycads, having as many as three or occasionally five or six (or more) fasciculate leaflets clustered at the nodes along the rachis (arising from a single point in a whorl and appearing as though they are divided) giving this cycad bamboo like appearance. The specific name "hildae" honors Hilda Guerra Walker, daughter of the commercial Collector Luciano Guerra who first collected this plant in the 1950s.
