Erie MetroParks was formed as the "Erie County Metropolitan Park District" in 1968 and adopted its current name in 1991. It consists of 13 individual park areas located throughout Erie County in the US state of Ohio covering approximately 3,254 acres (1,317 ha).
It was organized under the provisions of the Ohio Revised Code, Section 1545, as a separate political division of Ohio. Erie MetroParks is overseen by a Board of Park Commissioners consisting of three members appointed to three-year terms by Judges of the Probate Court and Common Pleas Court of Erie County. Its purpose, according to the statute, is to "preserve, conserve, protect, and enhance the natural and unique historical resources of the park district. Further, to provide opportunities for visitors and residents to use, enjoy, understand and appreciate these resources in a responsible, sustainable manner."
