The teen character will bow out on screen in a few weeks' time.
Young Emmerdale star Luke Roskell has left the show, Digital Spy can confirm.
The teen actor has filmed his final scenes after three years playing Sean Spencer on the ITV soap.
Speaking of his departure, Roskell told Digital Spy: "I have had an amazing three years on Emmerdale and I will miss everyone loads.
"I wanted to explore other opportunities and I am excited to find out what the future holds."
Emmerdale's series producer Kate Oates added: "We're sorry to see Luke go after three happy years on Emmerdale. He's been a joy to have as part of the cast, and we wish him tonnes of luck for the future."
Sean has had a busy year on screen, as it was his love triangle with Belle Dingle (Eden Taylor-Draper) and Gemma Andrews (Tendai Rinomhota) which led to an argument between the best friends which spiralled out of control.
In a tragic accident, Belle pushed Gemma over as they rowed over Sean, causing her to hit her head on a rock. Gemma later passed away as a result of her injuries.
More recently, Sean has decided that he wants to join the army, wanting to be just like his uncle Daz (Mark Jordon).
