Manzanita /ˌmænzəˈniːtə/ is a coastal city in Tillamook County, Oregon, United States. It is located on U.S. Route 101 about 25 miles (40 km) equidistant from Seaside to the north and Tillamook to the south. The population was 603 at the 2020 census.

The indigenous Tillamook people lived along the Oregon coast, including the Manzanita area (tidewaters of the Nehalem Bay), for about 12,000 years. They suffered from smallpox and other illnesses brought by white settlers, and the few remaining Tillamook people were relocated to the Siletz and Grand Ronde reservations in the 1850s.

At least two of Oregon's historical shipwrecks occurred off the Manzanita coast: the Glenesslin in 1913, and the Santo Cristo de Burgos (disappeared 1693) which has generated rumors of treasure buried on Neahkahnie Mountain.

Manzanita was platted as a beach resort in 1912. Manzanita post office was established in 1914 and named for the manzanita (Arctostaphylos sp.) plants that grow in the area. Manzanita means 'little apple' in Spanish.

On the morning of October 14, 2016, an EF2 tornado, which had begun as a waterspout, hit Manzanita. Many buildings in the town were damaged, but no injuries were reported. The mayor of Manzanita declared a state of emergency in response.

According to the United States Census Bureau, the city has a total area of 0.82 square miles (2.12 km), all of it land.
