Emmett Cullen (born Emmett McCarty in 1915 in Gatlinburg, Tennessee) is a member of the Olympic coven. He is the husband of Rosalie Hale, the adoptive son of Carlisle and Esme Cullen, the adoptive brother of Alice, Edward Cullen and Jasper Hale as well as adoptive brother-in-law of Bella Cullen and the adoptive uncle of Renesmee Cullen.

After being mauled by a black bear in 1935, Emmett was rescued by Rosalie, and given a second chance at life after being turned into a vampire by Carlisle at Rosalie's request. Rosalie and Emmett were rarely separated after this, having fallen passionately in love. The pair were integral members of the Cullen family and participated eagerly in removing the numerous impediments it faced. Like all Cullens, Emmett is a vegetarian vampire, and has gold eyes instead of red like vampires who drink human blood. Even considering the unstoppable physical strength of vampires, Emmett is physically the strongest in the family.
