Victoria Ekanoye will play Mistress Nightshade in "The Worst Witch".
The former "Coronation Street" star - who left her role as Angie Appleton earlier this year after 18 months in Weatherfield - will be part of the upcoming remake of the classic kids show.
Revealing the exciting news on Twitter, she wrote: "Delighted to say that I will be joining the coven of The Worst Witch and playing the fabulously flamboyant Mistress Nightshade.
"Well met #theworstwitch #mistressnightshade #narcissus @netflix @NetflixUK @bbc @cbbc (sic)"
Victoria's final "Corrie" scenes aired in January, and she took to social media at the time to thank her fans for their support.
Sharing a selfie with her on-screen tot Romeo Cheetham-Karcz, who played George Appleton, she tweeted: "And that's a wrap
Bye for now, from me and this beautiful little boy
Thank you to all of the @itvcorrie family, you made my 18 months better than I ever expected and I love the stinking lot of ya! (sic)"
Despite her exit, Victoria hinted she could make a return after her character split with husband Jude (Paddy Wallace) and returned to South Africa with their son George to get a fresh start.
She hinted Angie's connection to Adam Barlow (Sam Robertson) - who her alter-ego kissed in May 2018 - and on-screen mother-in-law Mary Taylor (Patti Claire) could prompt a comeback to the cobbles.
She previously said: "I've honestly had the time of my life and I can't believe it's been 18 months, it's felt like no time but I guess time flies when you're having fun.
"There was a lot of stuff left unresolved and I may or may not be able to confirm those things.
"Adam's going to go out to visit and Mary will because of the amazing connection she has made between Angie and George so we'll see."
