The Seattle Cascades were a charter franchise of World Team Tennis (WTT). The team first played as the Hawaii Leis in the league's inaugural 1974 season, before becoming the Sea-Port Cascades for the 1977 season, when it played half its home matches in Seattle, Washington and the other half in Portland, Oregon. The team left Portland in 1978, and played nearly all its home matches in Seattle. The Cascades announced the team would fold following the 1978 season.
