Trinidad is an unincorporated community and ghost town in Grant County, Washington.

The town is located between Quincy and Wenatchee atop a ridge overlooking the Columbia River.

At an elevation of 928 feet (283 m), Trinidad appears on both the Babcock Ridge and West Bar United States Geological Survey maps.

Trinidad is located on the border with Douglas County, directly above the Crescent Bar Resort on the Columbia River.

Though previously a ghost town, Trinidad has become a more popular location for new residential structures.
