The Western Promenade Historic District encompasses a late 19th-and early 20th-century neighborhood in the West End of Portland, Maine. This area of architecturally distinctive homes was home to three of the city's most prominent architects: Francis H. Fassett, John Calvin Stevens, and Frederick A. Tompson, and was Portland's most fashionable neighborhood in the late 19th century. The district was listed on the National Register of Historic Places in 1984.
