Alejandro Francisco Casañas Ramírez (born January 29, 1954) is a former Cuban hurdler.

At the 1977 Summer Universiade in Sofia he set a new world record in the 110 m hurdles with a time 13.21 seconds. This record would, however, only stand for two years. He could never fully copy the world-leading performance at the Olympic Games, where he won silver medals in 1976 and 1980.

His Cuban record time has later been improved by Anier García, Dayron Robles and Emilio Valle.^[1]
