Welcome to Avon Township


Avon Township is home to the Villages of Grayslake, Round Lake, Round Lake Beach, Round Lake Park, Round Lake Heights, Hainesville, & Third Lake. 

Every four years, the registered voters of Avon Township elect a Township Supervisor, Township Clerk, Township Assessor, and four Trustees to carry out the township’s business.
