The following are characters who first appeared in the BBC soap opera EastEnders during 2010, listed by order of first appearance. Executive producer Diederick Santer left EastEnders on 26 February 2010, handing over to Bryan Kirkwood, who fully took control from 1 March 2010.

Santer introduced five new main characters in January, three from the online spin-off EastEnders: E20, Zsa Zsa Carter (Emer Kenny), Leon Small (Sam Attwater) and Fatboy (Ricky Norwood), as well as two members of the long-established Mitchell family, Glenda Mitchell, played by Glynis Barber, and her son Danny (Liam Bergin). February saw the show's first birth of 2010, with Kamil Masood, the fourth child of the established Zainab Masood (Nina Wadia) and Masood Ahmed (Nitin Ganatra). The same month, Sandy Gibson (Caroline Pegg/Martha Cope), the mother of Dotty Cotton (Molly Conlin/Milly Zero) appeared. The character of Harvey Freeman, played by Martin Jarvis, was introduced in April, and the fourth main character from EastEnders: E20, Mercy Olubunmi (Bunmi Mojekwu), joined EastEnders in May. Kirkwood's first major casting was Zöe Lucker in the role of Vanessa Gold and later cast her daughter Jodie (Kylie Babbington) and husband Harry (Linal Haft), as well as Mercy's grandmother Grace (Ellen Thomas), all of whom appeared in June. June also saw the show's second birth of the year, that of Lily Branning, the daughter of Stacey Branning (Lacey Turner) and Ryan Malloy (Neil McDermott). In September, Richard Mitchell became the third birth of the year, born to Sam Mitchell (Danniella Westbrook/Kim Medcalf) and Jack Branning (Scott Maslen). Three characters arrived in October: Greg Jessop (Stefan Booth), Tanya Branning's (Jo Joyner) fiancé; Michael Moon (Steve John Shepherd), Alfie Moon's (Shane Richie) cousin; and Julie Perkins (Cathy Murphy), an old friend of Billy Mitchell (Perry Fenwick). In November, Kirkwood introduced Zainab's ex-husband, Yusef Khan (Ace Bhatti). Two more babies were born in December, James Branning and Tommy Moon, which triggered a long-running controversial storyline for Ronnie Branning (Samantha Womack) and Kat Moon (Jessie Wallace).
