The Western Promenade Historic District encompasses a late 19th-and early 20th-century neighborhood in the West End of Portland, Maine.

[2] Prominent among the purchasers of land in the area was Francis H. Fassett, the city's leading architect of the second half of the 19th century.

His own home stands at 117–119 Pine Street, and he is credited with a significant number of designs in the neighborhood.

[2] His house is a notable early example of the Shingle style, which Stevens had a major role in promoting, and his designs are also found throughout the area.

There are architect-designed examples of Second Empire, Italianate, Queen Anne, Colonial Revival, and Shingle styles, with a notable row of houses lining the Western Promenade.
