The Foster Memorial AME Zion Church is located on Wildey Street in Tarrytown, New York, United States.

[1] The first AME Zion congregation in Westchester was established in New Rochelle in 1837, with a White Plains group following six years later.

[1] Local builder and architect James Bird contributed the design, and the cornerstone was laid in October 1864.

Henry Foster died the next year, urging his wife to continue the church's development as he expected a large-scale migration of freed slaves from the South after the end of the war.

As was typical of the time, the cost was partly defrayed by charging for the pews, in this case an annual rent of $3.

The wave of southern blacks that her husband had anticipated finally materialized in the years afterwards, and during the Great Migration the church served as a community center for new arrivals in the Tarrytown area, helping them acclimate to an urban lifestyle.

The following decade the rear wing was added, expanding the available space in both the sanctuary and meeting room, and the original minister's apartment was converted into an auditorium.

Pastor Madison McRae continued the church's activist traditions, leading protests against housing discrimination and persuading the Tarrytown Fire Department to hire more African-Americans.
