Katie Austin is a model, certified fitness trainer, health coach, author, host and entrepreneur.


The daughter of fitness icon Denise Austin, she’s made a name for herself in the health and wellness space courtesy of the Katie Austin App, which hosts a library of hundreds of on-demand workout classes, recipes and lifestyle tips. Over the years, Austin has grown her brand to almost 2 million followers across all platforms, including her website, katieaustin.tv.


Austin first made her mark at SI Swimsuit with her 2021 Swim Search co-win alongside fellow model Christen Goff. The two also went on to share co-Rookie of the Year honors, with Austin earning the title following a magical shoot in Montenegro. Austin has returned to the magazine every year since, most recently joining the brand in Fort Myers, Fla., for the 2026 issue.
