Gray Atkins is a fictional character from the BBC soap opera EastEnders, played by Toby-Alexander Smith. He was introduced by executive producer Kate Oates in episode 5893, broadcast on 29 March 2019, as the patriarch of the Atkins family, which included Gray, his wife Chantelle, and children Mia and Mackenzie. Before his introduction and during the beginning of his time on the show, Gray was depicted as a charming and confident businessman, as well as a loving husband and committed father, before Gray and Chantelle became the focus of a storyline about domestic abuse. The show worked with charities such as Refuge and Women's Aid to depict the storyline in an accurate and sensitive manner. In September 2020, EastEnders announced that the storyline would end with Gray killing Chantelle to reflect the impact of the COVID-19 pandemic on domestic violence, which included a sharp increase in spousal murders.
