Hyeminseo (Korean: 혜민서; Hanja: 惠民署; MR: Hyeminsŏ) was the medical authority of the Joseon Dynasty in Seoul (then "Hanseong"), Korea.

[1] In 1392, the year of the foundation of Joseon, the organ was established to succeed the Hyemingoguk (혜민고국; 惠民庫局), the former medical institution of Goryeo.

In 1414, its name became Hyeminguk [ko], and then finally changed to the name Hyeminseo in 1466 under the reign of Sejo of Joseon.

Bureaucrats of Hyeminseo were also appointed through the gwageo recruitment examination.

Hyeminseo aimed to benefit the people but its coverage was limited to commoners living in Hanyang.
