Rhodophiala is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae). It consists of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile.
Rhodophiala species resemble small-flowered Hippeastrum or multiflowered Habranthus species. Their narrow parallel-sided leaves are differ from those of hippeastrums, being somewhat similar to those of large flowered Habranthus or Zephyranthes species.

Several species of Rhodophiala are cultivated as ornamental plants. From the cultivation point of view, Rhodophiala species can be separated into three main groups:
- The fall to spring growing Chilean species that need a dry summer dormancy, like R. bagnoldi, R. ovalleana, R. splendens, and R. advena. Some flower in fall before the leaves appear, others in spring at the same time as the leaves are produced. It is recommended that they are grown in frost-free conditions.
- The spring/summer growing species from the Andes of both Chile and Argentina where they experience a long dry winter under snow cover. They include R. rhodolirion, R. araucana, R. andicola, and R. elwesii. In most cases, they flower in spring at the same time as the leaves appear. It is recommended that they are grown in cool conditions during most of the year; they are not fully frost-hardy.
- The fall/winter/spring growing R. bifida from Uruguay and Argentina. It is dormant in the long hot summer in its native habitat, but receives rain all the year. It flowers in late summer before the leaves appear. Although hardy, it is intolerant of summer drought. A range of color forms is known; in the wild, most populations are of a single color.
