Alice Greczyn, born Alice Hannah Meiqui Greczyn on February 6, 1986, in Walnut Creek, California, is an American actress, model, and writer of mixed European and Asian descent, recognized for her roles in films and television during the 2000s and early 2010s.

The eldest of five children to parents Jane and Ted Greczyn, she was raised primarily in the Midwest before settling in Colorado, where she competed as a figure skater in her youth and was homeschooled, graduating high school early and enrolling at Front Range Community College at age 15 or 16 with aspirations to become a nurse.

Unable to take Colorado's nursing exam until 18, she pivoted to modeling after being scouted, relocating to California to pursue opportunities that soon expanded into acting.​

Alice Greczyn debuted in the 2004 teen comedy Sleepover as Linda, followed by a supporting role as Becky in Fat Albert that same year, and gained notice as Laurie Pullman in the 2005 action-comedy The Dukes of Hazzard alongside Jessica Simpson and Johnny Knoxville.

She appeared in horror films like House of Fears and Shrooms in 2007, then starred as Mary in the 2008 road trip comedy Sex Drive and as Annabel Drake in the action thriller Exit Speed.

Television roles included recurring parts as Alayna Collins on Quintuplets in 2004–2005, Frankie McMahon on the short-lived Windfall in 2006, Sage Lund on Lincoln Heights from 2007 to 2009, Mandy on Privileged in 2008–2009, and Madeline "Mads" Rybak as a series regular on ABC Family's The Lying Game from 2011 to 2013.​

Additional credits encompassed guest spots on CSI: Miami, Moonlight, Make It or Break It, The Young and the Restless in 2015, and Major Crimes in 2017, alongside modeling for Victoria Beckham's denim and eyewear line in 2011.

Raised in a Conservative Evangelical tradition, she later rejected it, detailing her experiences in the 2021 memoir Wayward: A Memoir of Spiritual Warfare and Sexual Purity, which inspired her podcast of the same name and the website Dare to Doubt, a resource for those detaching from harmful belief systems.

Standing at 5 feet 7 inches, she has largely stepped back from acting to focus on writing, advocacy, and personal passions like cooking and cultural exploration.​
