Jakob Mändmets (July 29, 1871 – December 25, 1930) was an Estonian writer and journalist.

He then worked in the counties of Saaremaa, Läänemaa and Harjumaa as a teacher.

From 1903 until its ban in 1905, he worked as an editor at the Estonian newspaper Uus Aeg, and then between 1906 and 1910 at Päevaleht.

A large part of his work he dedicated to the humble daily life on his native island of Saaremaa,[2] and became known for writing village stories like Night-herdsmen (1901), The Pastor Romer (1917), and Through the Underwood (1927).

Mändmets was the grandfather of physicist and academician Endel Lippmaa.
