State Route 544 is a state highway in northern Whatcom County, Washington, United States. It runs east–west for 9 miles (14 km) near the Canadian border, connecting SR 539 near Lynden to Everson and a junction with SR 9 in Nooksack.

The Lynden–Everson highway was built in the 1880s as a wagon road, with onward connections to Nooksack via a ferry over the Nooksack River that was later replaced with a bridge. It was paved by the Whatcom County government in the 1930s and incorporated into the state highway system in 1951 as a branch of Secondary State Highway 1A. During the 1964 state highway renumbering, the branch became SR 544. The Nooksack River bridge between Everson and Nooksack was replaced in 1994 after a major flood damaged the old structure.
