Oak Park operates under the Village Manager form of government, in which an elected legislative body, consisting of the President and a Board comprised of six Trustees, hires a professional manager to oversee the day-to-day operation of government services and programs, and to carry out the policy directives set out by the elected officials.

Regular Village Board meetings are at 7:30 p.m. and are usually held on the first and third Mondays of each month in Council Chambers at Village Hall, located 123 Madison Street at the corner of Lombard Avenue. All regular meetings of the Oak Park Village Board are telecast live on VOP-TV6, the Village's Government Information Cable Access Channel Six.
