Cupressus abramsiana (Santa Cruz cypress) is a rare North American species of trees in the cypress family. It is endemic to the Santa Cruz Mountains of Santa Cruz and San Mateo Counties in west-central California. When cypresses were discovered in the Santa Cruz Mountains in 1881, they were first identified as Cupressus goveniana, but Jepson (1909) considered them to be Cupressus sargentii. In a detailed analysis, Wolf (1948) concluded it was a distinct species, naming it after L. R. Abrams, Emeritus Professor of Botany at Stanford University.
