Halgerda is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
== Taxonomy == The genus Halgerda was classified within the family Halgerdidae by Odhner (1934). Halgerdidae Odhner, 1926, is treated as a synonym of Discodorididae in the taxonomy of Bouchet & Rocroi (2005). See also Valdés (2002). Seven species of Halgerda were described in the years 1880–1905, two species in 1932–1949, four species from 1975 to 1982, then 22 species in the years 1993–2001. In 2018 another six new species were described from Mozambique, highlighting the number of undescribed species on the African coast of the Indian Ocean. A number of undescribed species are known and many species show considerable variation across their ranges, which may indicate that more cryptic species exist.
