Auston Levi-Jesaiah Trusty (born August 12, 1998) is an American professional soccer player who plays as a center-back or left-back for Scottish Premiership club Celtic and the United States national team.

[5] In 2016, Trusty signed an amateur United Soccer League contract with the Philadelphia Union reserve affiliate Bethlehem Steel.

[6] The contract with the Steel allowed Trusty to remain eligible to play college soccer with the North Carolina Tar Heels.

On November 20, 2019, Trusty was traded to the Colorado Rapids in exchange for up to $750,000 in allocation money, including performance-based thresholds, as well as a percentage of a future transfer.

[16][17] He played his last game for the Rapids on July 5, returned to Arsenal, and was immediately loaned to EFL Championship club Birmingham City for the 2022–23 season.

[30][31] He missed the second group game through suspension, and was an unused substitute for the third, a 4–1 loss to Chile that confirmed the United States' elimination from the tournament.

[34] On December 20, 2018, Trusty, alongside then teammate Mark McKenzie, received his first call-up to the senior United States squad for their January 2019 camp.

Partnering McKenzie in central defense, Trusty played the whole game, and provided the assist for Weston McKennie's second goal of the 7–1 win.
