Madrepora (Spanish, "mother of pores") is a genus of stony corals, often found forming reefs or islands in tropical locations.
The names Madrepore and Madreporaria were formerly applied universally to any stony coral of the family Scleractinia.
They reproduce in three separate ways, as discovered by the marine zoologist Anne Thynne (1800–1866).
A colony is branched with small polyps in cylindrical cups separated by a perforated coenosteum.
Madrepora is economically important, since it contributes to the formation of coral reefs.
