The Jacob Wentz House is a historic building located in Iowa City, Iowa, United States. Wentz was a German immigrant and a shoemaker by trade. This is one of the few native stone houses in Iowa City, and being two stories, rarer still. It is a fine example of the Greek Revival style, featuring symmetrical openings, dressed stone lintels, and a bracketed entablature. Originally a single family residence, it was converted into apartments and it now houses a retail business, The Haunted Bookshop. The house was listed on the National Register of Historic Places in 1974.
