Association Park is the name of two different baseball grounds which were located in Kansas City, Missouri, United States.

[Kansas City Times, May 1, 1886, p.5] By 1888, between the frequently poor showing of the various teams, along with the tendency of the low-lying field to accumulate smelly, swampy water, local papers had considerably changed their tune, calling it, "One of the worst base ball parks in the country."

This ballpark was home to the Kansas City Blues American Association entry during 1903 through the early weeks of the 1923 season.

[Kansas City Journal, March 19, 1903, p.7] As construction proceeded, a contest was held to allow the public to name the ballpark.

[Kansas City Journal, July 7, 1925, p.2] The lot was eventually converted into a public playground, called Blues Park.
