The 2023 Orange County SC season was the club's thirteenth season of existence, and their thirteenth consecutive season in the United Soccer League Championship, the second tier of American soccer.
Orange County had a tumultuous start, only winning one out of their first eight games with a 1-4-3 record, leading to the team firing head coach Richard Chaplow and promoting the newly hired assistant coach Morten Karlsen to interim head coach on May 1, 2023.[2] Under new management, Orange County found form and finished the season on a three-game winning streak, going from 11th to 2nd place in the Western Conference,[3] and having a final record of 17–11–6.[4]
In the first round of the USL Championship playoffs, Orange County faced off against seventh seeded El Paso Locomotive FC at home, winning 1–0 with a goal from Forward Milan Iloski.[5] In the semifinals, Orange County hosted 6th seed Phoenix Rising FC, losing 2–1 in extra time to the eventual champions.[6] [7]
This would be the last season that the team-leading goalscorer and All-League Second Team[8] Iloski would play for Orange County, as after this season he made a transfer to FC Nordsjælland in the Danish Superliga in the January transfer window.[9] [10] Additionally, on November 10, appointed interim head coach Karlsen was signed to become the official head coach of Orange County.[11]
