Johan is a meadow mill on the Westfriese Omringdijk near Schellinkhout in the Dutch municipality of Drechterland. It is not far from De Grote Molen.
It was originally built in 1956 at the Weeltje in Hoorn, as a successor to a blown-down meadow mill at a farm there. When the farm was demolished in 1964 to make way for housing, the mill was moved to the Julianapark in Hoorn, where it fell into disrepair. In 1985, the Johan was moved and partly rebuilt at the location where it stands today. It drains the local natural ice rink and part of the polder.
After the move to its current location, the mill was named after Johan Kerkmeijer, who initially managed to save it from demolition in Hoorn.
