The Union Arcade is an apartment building located in downtown Davenport, Iowa, United States. The building was individually listed on the National Register of Historic Places in 1983 by its original name Union Savings Bank and Trust. Originally, the building was built to house a bank and other professional offices. Although it was not the city's largest bank, and it was not in existence all that long, the building is still associated with Davenport's financial prosperity between 1900 and 1930. From 2014 to 2015 the building was renovated into apartments and it is now known as Union Arcade Apartments. In 2020 it was included as a contributing property in the Davenport Downtown Commercial Historic District.
