Euctemon was an Athenian astronomer. He was a contemporary and collaborator of Meton, who developed the 19-year Metonic cycle, which synchronises 235 lunar months with 19 solar years to form the basis of ancient Greek calendrical systems. Little is known of his work apart from his partnership with Meton and what is mentioned by Ptolemy. With Meton, he made a series of observations of the solstices. Geminus and Ptolemy quote him as a source on the rising and setting of the stars. Pausanias's Description of Greece names Damon and Philogenes as the children of Euctemon.
