We are very excited to celebrate 175 years of
service to the citizens of McHenry County!
The McHenry County Sheriff's Office has served
McHenry County residents since 1837. The first jail consisted of
two cells run by two deputies. The Sheriff and his family lived in
the building and the Sheriff's wife cooked the inmates' meals. Click

technologically advanced departments in the state.
