Midridge is an unincorporated community in northeastern Shannon County, Missouri, United States. It is located on a county road about sixteen miles northeast of Eminence. It formerly had a post office/General Store, but that is closed and mail is now delivered to the community from Bunker. Midridge now consists of two houses and the old storebuilding, one occupied. There was an old one room school house in the 1930s and early '40's, but it burnt down. School was then held in the house owned by the store keeper, who was a relation to the teacher.
