Leo Valentine is a fictional character from the British Channel 4 soap opera Hollyoaks, played by Brian Bovell.

On 6 September 2007, Leo's former girlfriend, Valerie Holden (Samantha Giles), turns up with his illegitimate children Danny (David Judge) and Lauren Valentine (Dominique Jackson).

Leo's other children Calvin (Ricky Whittle) and Sasha (Nathalie Emmanuel) are horrified to discover their father cheated on their mother and that they have two more siblings.

In 2009, after Warren Fox's (Jamie Lomas) death, his foster brother Spencer Gray (Darren John Langford) moves in with the Valentines.

To make matters worse, Lauren collapses and falls down the stairs at The Loft during an argument with Sasha about her scheme to fleece Spencer out of his inheritance.

In July 2014, Sonny (now played by Aaron Fontaine) informs his current fiancée Carmel McQueen (Gemma Merna) that Leo has provided him with a financial deposit for the two of them to purchase a household of their own in the village.
