New York City-born Erin Moriarty launched her acting career in a way many hopefuls dream of: with an awards-recognized project. Erin first appeared on screen in the Emmy-nominated soap opera
One Life to Live (1968) in 2010, playing the character Whitney Bennett in six episodes.
In 2011 she built on her TV work with a guest role in an episode of
Law & Order: Special Victims Unit (1999).
The following year, Erin landed a small part in her first feature film. Acting alongside
Ben Stiller,
Vince Vaughn and
Jonah Hill, she appeared in the sci-fi comedy
The Watch (2012). In 2013, she took another supporting gig in a movie. The coming-of-age drama
The Kings of Summer (2013) follows three teenagers who hatch a plan to part ways with their parents and live off the land in a house built by themselves. Portraying Natalie Walraven, the daughter of
Radha Mitchell's character, Erin also worked on the 2013 TV series
Red Widow (2013).
She stayed in TV in 2014 and played the daughter of
Woody Harrelson's hard character Marty Hart in the first season of the Emmy-winning and Golden Globe-nominated
True Detective (2014). It was a role that required her to appear in three episodes. Since the show wrapped, Erin has said playing a Goth was "fun... because it's the opposite of how I present myself, and is the opposite of any role I'd been considered for." In 2015, Erin landed a recurring guest role on hit Netflix crime action series
Jessica Jones (2015). In 2016's
Captain Fantastic (2016), starring
Viggo Mortensen, she played the supporting role of Claire in the film festival favorite about the changing dynamics of a unique family. Erin followed that up with the action thriller
Blood Father (2016), starring
Mel Gibson and
William H. Macy. She went on to play a starring role as Kelly in the biopic
The Miracle Season (2018) (2018), alongside
Helen Hunt. As of 2019, she is co-starring in Amazon Prime's 'The Boys'.
