Kennedy Park is a large, multi-use park in Hayward, California, managed by the Hayward Area Recreation and Park District (HARD).^[1] It is the most heavily used park in the district.^[2] The park is adjacent to McConaghy Park, which contains McConaghy House, a historic property, built in 1886, and managed as a house museum by HARD and the Hayward Area Historical Society.^[3] McConaghy House features Stick/Eastlake architecture. It lies within San Lorenzo. In 2013, plans to renovate the park and combine the park and house into a Victorian-style venue were proposed.^[4]

Kennedy Park contains a merry-go-round, a petting zoo, a pony ride, and a 2 ft (610 mm) narrow gauge railroad with a train pulled by a Chance Rides C.P. Huntington locomotive. There are also picnic and activity areas, as well as a snack bar. The park is open every day during the summer and on the weekends during the rest of the year, weather permitting.
