The 27-year-old's character, also called Cameron, will arrive on screen in June and immediately shake up life in the village.
Cameron's initial storyline will see him become a love interest for firefighter Leela Lomax (Kirsty-Leigh Porter). This makes him a rival for charmer Ziggy Roscoe (Fabrizio Santino), who also has feelings for Leela.
The newcomer is originally from Scotland, but his presence in Chester may not be good news for everyone as he has recently spent time in prison.
While Cameron won't be a new villain in the village, viewers will discover that he has a dark and complex past.
A Hollyoaks source explained: "Cameron comes into Hollyoaks as a stranger with a dangerous past that will have wide-ranging implications for many characters in the village.
"He grew up near Edinburgh but after spending time in prison found his way to Hollyoaks. What has drawn him to the village is a mystery to most, but not all of the residents."
Moore is also originally from Scotland but grew up in Gloucestershire.
The actor's previous credits include a role in E4's My Mad Fat Teenage Diary, as well as parts in short films and theatre productions.
