Crabtree is an unincorporated community in Linn County, Oregon, United States. Although it is unincorporated, it has a post office with a ZIP code of 97335. Crabtree lies off Oregon Route 226 10 miles east of Albany.
The town received its name when the Southern Pacific Railroad came there. Crabtree Creek and Crabtree Lake in Linn County were named for pioneer John J. Crabtree, a native of Virginia, who arrived in the Oregon Country in 1845. He wintered in the Tualatin Plains, then bought the William Packwood Donation Land Claim east of the forks of the Santiam River in the spring in 1846. The station and community were named for John Crabtree's cousin Fletcher Crabtree.
