The Simon Abraham Duplex is a historic house located in Portland, Oregon, United States.

Built in 1890 in the Queen Anne style, it is one of few duplexes in the Eliot neighborhood remaining from the late-19th to early-20th centuries.

Its early ownership by German Americans and Scandinavian Americans testifies to the settlement by ethnic immigrants in this part of the former city of Albina.

[2] The duplex was listed on the National Register of Historic Places in 1999.
