Zephyranthinae was a subtribe of plants classified under the tribe Hippeastreae. It belonged to the subfamily Amaryllidoideae of the Amaryllis family ( Amaryllidaceae). They are generally small plants with solitary flowers. Spathes are fused forming a tube surrounding the pedicel of the flower. Most of its members were commonly known as rain lilies. It included four genera:
- Zephyranthes Herb. - Rain lilies.
- Cooperia Herb. - Rain lilies. It is sometimes considered a subgenus of Zephyranthes.
- Habranthus Herb. - Rain lilies.
- Sprekelia Heist. - Aztec lilies.
Members of the former genus Haylockia are now classified under Habranthus. Pyrolirion (fire lilies), once often included under Zephyranthes, is now considered to be a distinct genus and placed in the tribe Eustephieae.
Following the application of molecular phylogenetics the subtribe was found to be polyphyletic and subsequently dispersed amongst two other Hippeastreae subtribes.
