Crossley, who has portrayed Scarlett Nicholls since 2007, revealed via her Twitter page that she was waiting for news on an audition.
The 18-year-old posted: "The most stressful part of auditions is waiting for a verdict! Ahh ha! X (sic)."
When asked if this meant she was leaving Emmerdale, Crossley confirmed that she would be exiting the show.
After a series of well wishers contacted her, she added: "Thanks guys, had to announce because I didn't know how to reply to the tweets asking about storylines. Love you all and the support xxxxxx."
Crossley is one of a number of actors to confirm their departure from Emmerdale in recent months, with Suzanne Shaw recently announcing that she is leaving after a year on the programme.
