Rainier (pronounced: /reɪˈnɪər/ - ray-NEAR) is a cultivar of cherry. It was developed in 1952 at Washington State University by Harold Fogle, and named after Mount Rainier. It is a cross between the 'Bing' and 'Van' cultivars.

'Rainiers' are considered a premium type of cherry. They are sweet with a thin skin and thick creamy-yellow flesh. The cherries are very sensitive to temperature, wind, and rain. About 1/3 of a 'Rainier' cherry orchard's crop is eaten by birds.

The standard root stock for the 'Rainier' cherry is the Mazzard cherry, a wild or seedling sweet cherry used as grafting stock. Mature 'Rainiers' reach a height of 30 to 35 feet and are widely adaptable to a variety of soil types. Trees should be well spaced to provide maximum sun exposure for individual branches, ensuring fully developed, sweet, ripe fruit at harvest time. 'Rainiers' will produce fruit in 3 to 5 years, with a bloom period in early April. The creamy light yellow to medium yellow-orange fruit develops a red blush and is ready to harvest late-June through early-July. 'Rainier' cultivars require pollination. Typical pollinators are the 'Bing', 'Van', 'Lapins', 'Black Tartarian' and 'Lambert' cultivars. 'Rainiers' grow best in USDA Zones 4-9.
