Claquato Church is a historic Methodist church building located off of Washington State Route 6 in Claquato, Washington. It is the oldest standing church building in the state of Washington. It was built in 1857 with a louvered belfry and crown steeple modeled after mid-nineteenth century New England meeting houses. The pulpit and pews were hand crafted. When the county seat moved from Claquato to Chehalis in the 1870s, the church lost its congregants and stood vacant until the 1950s, when it was restored. The building was added to the National Register of Historic Places in 1973.
