The Lincoln Park Grounds, commonly known as Union Grounds, was a former baseball park, part of Lincoln Park, located in Cincinnati, Ohio. The Grounds were built for the Union Cricket Club in 1856; they "were used for cricket and baseball in the summer and were flooded for skating in the winter." In 1865 Harry Wright became the professional of the Cincinnati Cricket Club, which also used the grounds, and the next year Aaron Champion, president of the new Cincinnati Base Ball Club, "approached Wright to propose a limited use of the grounds if the CBBC and Live Oaks club would put in $2000 each to revamp the Lincoln Park Grounds."
