Evaline is an unincorporated community in Washington, United States, south of Napavine and 3 miles north of Winlock on State Route 603.

The earliest white settlers in this area were the Urquharts and the MacDonalds. Sedate W. Porter founded the town and established the post office on Feb. 14, 1906, which was open until 1930. The Northern Pacific Railroad began operations from Kalama to Evaline, a 25 miles stretch, in 1872.

The town was named after Porter's wife, Evaline. However, the name was registered misspelled as "Eveline" and the railroad company used the incorrect spelling for some time.

The Hope Grange was founded in Evaline in March 1904. Named as such to "boost courage and hopes", a hall was built soon thereafter, and the grange officially incorporated in June 1948.

The Evaline School District (ESD) began in 1883 and oversees the two-room K-6 Evaline Elementary School. Middle school and high school students attend schools in Winlock. The ESD is the longest, uninterrupted operating school district in the county.

The original schoolhouse was a log cabin, and replaced in 1890 by a one-room school building after it was lost due to damages by a falling tree. Known at first as Brown's School, it was renamed after the town. The school underwent several revisions in the early 20th century, being replaced in 1908 with a two-room building and a four-room addition in 1913. The current schoolhouse was constructed in 1925 after a large fire of the previous structure. The Evaline School is one of the last such schools in the state.
