Dylan Keogh is a fictional character from the BBC medical drama Casualty, played by William Beck. He first appeared in the twenty-fifth series episode "Only Human", broadcast on 12 March 2011. The character was introduced as a replacement for fellow emergency medicine doctor Ruth Winters (Georgia Taylor). Beck had briefly attended medical school before becoming an actor, and he felt the role was right for him. Dylan is a Consultant in emergency medicine and a member of Holby City Hospital's emergency department staff.

Dylan is portrayed as being abrupt, sarcastic, rude and uncaring, which has led some viewers to speculate that Dylan has Asperger syndrome. Upon joining the cast, Beck was told by the producers that Dylan should not smile. He also felt that he understood where Dylan is coming from. Dylan enjoys his work and likes to take on the more unusual cases and medical mysteries. He lives on a house boat with his dog Dervla. During his time in the ED, Dylan has developed strong friendships with Zoe Hanna (Sunetra Sarker) and Lofty Chiltern (Lee Mead).

Dylan's estranged wife Sam Nicholls (Charlotte Salt) was introduced to the ED in late 2011. They had a troubled relationship, which deteriorated further once Sam filed for divorce and began to affect their work. Dylan hoped that they might reconcile, but Sam soon began dating Tom Kent (Oliver Coleman). The character departed the show in late 2012, after struggling to be around Sam, who he still loved. Two years later, in 2014, Beck reprised the role and admitted that he was relishing the chance to play Dylan again.
