Syagrus is a genus of Arecaceae (palms), native to South America, with one species endemic to the Lesser Antilles.

Those species that have upright trunks grow 2–36 metres (7–118 ft) tall with stems that are 6–35 centimetres (2.4–13.8 in) in diameter.

[8] As of May 2024[update], Plants of the World Online accepted the following species and hybrids:[2] Syagrus is an almost entirely South American genus.
