The 25-year-old actor joined the soap in June last year as jack-the-lad ladies' man Callum Monks.
Upon his arrival, Callum immediately took a shine to Stacey Slater (Lacey Turner), who eventually told her husband Bradley Branning (Charlie Clements) that she no longer loved him. In an attempt to move on, Stacey embarked on a rocky romance with her new flame.
Jordan, who has already finished filming with the Walford-based soap, will remain on screen until early spring.
A source told DS: "Viewers will learn a little more about Callum before he leaves Albert Square behind. It won't be long before we see Elliott back on television, though - he already has something else lined up."
Speaking of his departure, he said: "I've had a really great time at EastEnders and I've enjoyed working with all the cast. I've loved every minute of it and I’m looking forward to trying new things."
His screen father Vinnie Monks - played by comedian Bobby Davro - quit the show in July, before bowing out on screen in November.
New arrivals in E20 over the next few months include Syd Chambers (Nina Toussaint-White), Manda Best (Josie Lawrence) and Theo Kelly (Rolan Bell).
