The subserosa or tela subserosa, is a thin layer of tissue in the walls of various organs. It is a layer of connective tissue (usually of the areolar type) between the muscular layer (muscularis externa) and the serosa (serous membrane).

Anatomical terminology [edit on Wikidata]

The subserosa has clinical importance particularly in cancer staging (for example, in staging stomach cancer^[1] or uterine cancer).

The subserosa (sub- + serosa) is to a serous membrane what the submucosa (sub- + mucosa) is to a mucous membrane.
