The Everett AquaSox are a Minor League Baseball team in Everett, Washington. The team is a member of the Northwest League and is affiliated with the Seattle Mariners. The AquaSox play their home games at Funko Field, which has a seating capacity of 3,682. Everett has won three division titles and one Northwest League championship.

Following the 1983 season, Bob and Margaret Bavasi purchased the struggling Walla Walla, Washington, based Blue Mountain Bears.^[3] Antiquated facilities compounded by dwindling attendance in Walla Walla prompted the new owners to move the franchise. The Bavasis, who had secured affiliation with the San Francisco Giants, ultimately selected Everett as the relocation destination.^[4] Playing as the Everett Giants, the club was affiliated with San Francisco for eleven years until 1994. After the 1994 season, Everett signed a player development contract with the Seattle Mariners as their Class A Short Season affiliate and adopted a new unique name, the AquaSox. Since the 2021 season, the team has played at the High-A classification as a Mariners affiliate.^[5][6]

Due to the Northwest League's reclassification in 2021 as a High-A league, which included an expanded schedule and new venue requirements, the AquaSox began exploring a replacement for Funko Field. In September 2022, the City of Everett and Snohomish County approved funds to study a new stadium, which is estimated to cost $80 million and seat 3,500 spectators.^[7] A site adjacent to Angel of the Winds Arena in downtown Everett is under study; other proposed sites included the Everett Mall, Kasch Park, and a city-owned lot near Interstate 5.^[8][9]

One of the team logos, used on road caps and jerseys, is based on the "trident" insignia used by the Mariners in the early 1980s (rotated to look like the letter "E" for Everett, instead of "M" for Mariners). Their mascot is Webbly, a frog.^[10] According to long-time team radio broadcaster Pat Dillon, "The frog is a cross between a Pacific tree frog and a Central American red-eyed tree frog—and Brooks Robinson."^[11] Previously, the mascot for the Everett Giants was a giant hot dog named Frank.
