Greendale is a village in Milwaukee County, Wisconsin, United States.

The first recorded inhabitants of the Greendale area were various Native American tribes, including the Potawatomi.

[6] Greendale was one of three government-sponsored "Greenbelt" communities constructed by the Resettlement Administration, starting in 1936, as part of President Franklin Roosevelt's New Deal.

The planners and selection committees excluded African-American families from renting homes and created a racially segregated and all-white suburban community.

[8] The original downtown area included the village hall, built in a Colonial Williamsburg style, 366 new homes comprising 572 living units, and several businesses.

[9] The Greenbelt communities were patterned after the British garden city movement urban planning concept, built so residents could walk to schools, shops, and parks.

[11] In the late 1950s Greendale experienced growth in conjunction with the expansion of the Milwaukee suburbs as a whole.

Although new homes were built and the number of minority families increased in Milwaukee County, racially restrictive covenants were used to maintain the all-white Greendale community.

In 1958, the Crestview Acres land was sold by Elroy H. Barbian for development with the restrictive covenant that only white families could purchase the homes.

[13] More than 40,000 flowers are planted annually along the downtown streets in hanging baskets, sidewalk beds, and storefront window boxes.

The downtown village center has more than a dozen independent shops [24] and nine places to eat.

[25] Community members are active in many local civic organizations, church groups and school committees where they volunteer their time and talents for the betterment of the Village.

Whitnall Park offers many recreation options including: Part of the Root River Parkway is in Greendale.

[52] The Village is also connected to the Milwaukee County Park System Oak Leaf Trail, a paved 135-mile (217 km) multi-use recreational trail system, which provides opportunities for walking, running or biking.

The Rock Sports Complex, an athletic park in Franklin, Wisconsin, comprising baseball fields, mountain bike & BMX trails & snow play areas, borders Greendale on the southern boundary of the village.

Greendale is represented in the United States Senate by Senators Ron Johnson (R) and Tammy Baldwin (D) and falls within Wisconsin's 1st congressional district, which is represented by Bryan Steil (R).

The Greendale High School Marching Band was invited to appear in the 2023 Macy's Thanksgiving Day Parade.
