The John Jacob Astor Hotel, originally known as the Hotel Astoria, is a historic former hotel building located in Astoria, Oregon, United States, and listed on the National Register of Historic Places (NRHP). It is one of the tallest buildings on the Oregon Coast and is a "prominent landmark" in Astoria. Constructed in 1922–23, the hotel opened in 1924 and initially was the city's social and business hub, but soon was beset with a variety of problems, and struggled financially for years. It was renamed the John Jacob Astor Hotel in 1951, but a decline in business continued, as did other problems. The building was condemned by the city for safety violations in 1968 and sat vacant for several years until 1984, when work to renovate it and convert it for apartments began. It reopened as an apartment building in 1986, with the lowermost two floors reserved for commercial use.
