Sarah-Louise Platt (also Tilsley and Grimshaw) is a fictional character from the British ITV soap opera, Coronation Street. She was born on-screen during the episode broadcast on 2 February 1987. She was played by Leah King in 1987 and by Lynsay King from 1987 until 8 October 1999 when King opted to leave to focus on her education. Tina O'Brien took over the role on 31 October 1999; she opted to leave in 2007 and made her final on-screen appearance on 30 December 2007. A number of false rumours about O'Brien returning to the role surfaced during her absence from the serial. In October 2014, it was announced that O'Brien had reprised the role, she returned to filming in February 2015 and returned on screen on 30 March 2015.

Sarah is the daughter of Gail (Helen Worth) and Brian Tilsley (Christopher Quinten), sister to Nick Tilsley (Warren Jackson, Adam Rickitt, Ben Price) and half-sister to David Platt (Thomas Ormson, Jack P. Shepherd), granddaughter to Audrey Roberts (Sue Nicholls), Ted Page (David Byrne) and Bert and Ivy Tilsley (Lynne Perrie) and mother to Bethany (Mia Cookson, Amy & Emily Walton, Lucy Fallon), Billy and Harry. Sarah's storylines have included a controversial and ground-breaking underage pregnancy which saw her giving birth to Bethany Platt and saw Sarah deal with motherhood in her teens, internet grooming, her friendship with Candice Stowe (Nikki Sanderson), her relationships with Todd (Bruno Langley) and Jason Grimshaw (Ryan Thomas) as well as her sibling rivalry between her and her half-brother David. Her exit storyline saw her leave Weatherfield to start a new life with Bethany in Milan. Her return storyline saw her track down Bethany who had run away from home and returned to Weatherfield, and her storylines since then have seen her begin a relationship with brother David's enemy Callum Logan (Sean Ward) which later resulted in her feuding with Callum and falling pregnant with his child and help to cover up Callum's murder after her sister in law Kylie (Paula Lane) kills him. Storylines after that saw her give birth to Callum's son, Harry, develop postpartum psychosis afterwards and have an on-and-off relationship with neighbour Gary Windass (Mikey North), who is a former nemesis of her brother David. Sarah was a central character in the show's third live episode which was aired to commemorate 60 years of ITV in September 2015.
