Small Polyp Stony (SPS) coral is a category of saltwater corals. They fall under the classification order Scleractinia, a calcifying coral which produces a hard skeleton as it grows. The term is derived from the two categories into which Scleractinia corals are placed, small polyp stony (sps), and large polyp stony (lps). SPS is the smaller by number of scientific families than LPS, however the diversity within those of SPS is much broader. The appearance of corals within this grouping can have large differences in all characteristics.

The Families of order Scleractinia that fall under the grouping of SPS include the following.
