SEATTLE — The Seattle Mariners are gearing up for a monumental celebration as they prepare to commemorate their 50th season in 2026.

The franchise announced a series of events, headlined by the 50 Seasons Celebration Weekend from Aug. 7-9 at T-Mobile Park. This special weekend will feature a pregame ceremony on Aug. 8 to honor the Top 50 Greatest Mariners Players, alongside a lineup of 50 Seasons giveaway items and promotions throughout the season.

Throughout the 2026 season, the Mariners will sport a “50 Seasons” patch on their jerseys, replacing the primary logo on the sleeves.

The 50 Seasons logo is rich with symbolism, featuring elements that represent the franchise’s history, including a ring of 116 lines in honor of the 2001 team’s AL-record 116 wins, a hidden Mount Rainier, and the original typeface from the team’s inaugural 1977 season.

“Celebrating 50 seasons of Mariners baseball is a tribute to the generations of fans, the community, and the Mariners players who have defined this franchise,” said Mariners President of Business Operations Kevin Martinez. “Their passion, dedication, and belief have carried this franchise for the past half-century, and their passion fuels our excitement for not only our 50 Seasons celebration, but also the next 50 years of Mariners baseball.”

The Mariners also launched a 50 Seasons Collection at their team stores Wednesday. The collection includes Mariners 50 Seasons caps, apparel, and baseballs, with more gear arriving throughout the holidays and into 2026.
