The Richard J. Coffee Mercer County Park is a recreational park located mostly within West Windsor in Mercer County, New Jersey. Originally and still more commonly known as simply Mercer County Park, it was renamed for New Jersey State Senator Richard J. Coffee on October 15, 2009. The park encompasses over 2,500 acres (10 km²) covering much of southern West Windsor, with portions extending into adjacent Hamilton and Lawrence. Mercer Lake, located within the park, is the home for the US Olympic Rowing Team's training center. The National Softball Association awarded the Mercer County Park Commission with its "Outstanding Parks Award" for the softball fields and facilities in Mercer County Park.
