A somatomammotroph or somatomammotrophic cell, also known as a somatolactotroph or somatolactotrophic cell, is a type of cell of the anterior pituitary gland that produces both somatotropin (growth hormone) and prolactin. Cells that secrete only somatotropin or only prolactin are known as somatotrophs and mammotrophs, respectively.

Approximately 15-20% of the cells in the normal pituitary gland are somatomammotrophs.{{cite journal |last1=Bassetti |first1=M. |last2=Brina |first2=M. |last3=Spada |first3=A. |last4=Giannattasio |first4=G. |title=Somatomammotropin cells in GH-secreting and PRL-secreting human pituitary adenomas |journal=Journal of Endocrinological Investigation |date=November 1989 |volume=12 |issue=10 |pages=705–712 |doi=10.1007/BF03350037 |pmid=2614009 |s2cid=22609466 |url=https://link.springer.com/article/10.1007/BF03350037 |access-date=27 January 2023|url-access=subscription }}
