In Greek mythology, Macar (also Macareus) was the son of Aeolus and Enarete, brother of Canace. Canace was killed by Aeolus after she fell in love with Macar.

Macar was also one of the Heliadae, a son of Rhodus and Helios. Macar, along with his brothers, Triopas, Actis and Candalus, were jealous of a fifth brother, Tenages's, skill at science. They killed him. Macar escaped to Lesbos, where he became became King, and took over many of the neighboring islands. Lesbos, the god of the island, came to the island and married Macar's daughter, Methymna.

Other traditions claim Macar was a son of Crinacus.

It is uncertain to what degree these three Macars, sons of Crinacus, Aeolus and Helios, are the same person. It is also not known if any of these Macars are the one who accompanied Odysseus on the Odyssey. Ovid XIV, 159
