Ashlyn Miller

College career Miller played for the Texas Longhorns women's soccer team. She totaled 20 appearances as a freshman and registered 4 starts. She scored her first collegiate goal on November 7, 2021, converting a long-range shot against TCU in the Big 12 championship match. Miller had an increase in playing time in her sophomore year, starting in 15 of her 21 appearances. She played 90 minutes in all four of Texas' Big 12 and NCAA tournament matches. Over the course of the season, Miller shifted into a more significant leadership role both in games and off the field; her movement into the limelight was partially due to the injury and subsequent absence of future San Diego Wave teammate Trinity Byars. Miller ended up helping Texas cap off their first year in the SEC by winning the conference title.

Club career Miller signed her first professional deal, a national team replacement contract, with San Diego Wave FC on July 8, 2025. On 3 January 2026, she scored her first A-League goal in an eventual 2–2 draw with the Wellington Phoenix. Later in the same month, Miller recorded a last-minute equalizer against Melbourne City to salvage a point in the 87th minute of the match.

On July 31, 2026, it was announced that Miller had signed with USL Super League club Brooklyn FC. She made her Super League debut on August 15, 2026, earning the start in Brooklyn's season-opening defeat to Lexington SC.
