Seahaven is an extinct town in Pacific County, in the U.S. state of Washington.
Seahaven was established around 1899, with land owned by realtor Thomas Potter. Located at the mouth of the Willapa River,[1] it was mapped by Potter, who leased properties there and in South Bend.[2] By 1890, the town had established a bank as well as a newspaper publisher.[1] In September 1890, a post office was established, with Granville S. Loomis serving as the postmaster.[3] It remained in operation until 1891.[4] Following Potter's death in 1901, his will was left with a 63-year-old woman he was going to marry, which included the grounds of Seahaven.[2] [5] Seahaven eventually went extinct by the early 20th century, with its businesses either closing down or relocating to South Bend.[1]
