Andronicus of Cyrrhus or Andronicus Cyrrhestes (, "Andrónikos Kyrrhēstou"), son of Hermias, was an ancient Macedonian astronomer who flourished about 100 BC. He is best known as the architect of the horologion at Athens called the Tower of the Winds. Andronicus also built a multifaced sundial in the sanctuary of Poseidon on the Greek island of Tinos.
