Cleobulus of Lindos was a 6th-century BCE Greek sage and tyrant of Lindos on Rhodes, traditionally numbered among the Seven Sages of Greece. Celebrated for his strength and beauty and claiming descent from Heracles, he was known for his poetic riddles and for the education of his daughter, Cleobuline, who was also a riddler.

As with other archaic sages, the historical details of his life are sparse and legendary. His literary output survives only in fragments. He composed riddles in verse, most famously the "riddle of the year". He is also credited with a bronze tomb epigram for Midas, though its authenticity was questioned even in antiquity.

Cleobulus’s significance stems from his canonical status as one of the Seven Sages, representing the tradition of poetic and riddling wisdom within that group. The endurance of sayings attributed to him underscores his role in the archaic tradition of wisdom literature.
