Polycarpon is a genus of flowering plants in the pink family. They are known generally as manyseeds. There are roughly 9 to 15 species, representing most continents.^[1] The best-known species is perhaps Polycarpon tetraphyllum, which is native to southern Europe but is present in many other regions as an introduced species. These plants are low, matted annuals spreading slender stems along the ground or erect with many branches.

Species include:

• Polycarpon depressum - California manyseed
• Polycarpon prostratum
• Polycarpon succulentum
• Polycarpon tetraphyllum - fourleaf manyseed
