The Cadillac XT6 is a mid-size luxury crossover SUV with three-row seating manufactured by General Motors. The vehicle was introduced on January 12, 2019, at the North American International Auto Show. It went on sale in June 2019 as a 2020 model.

The North American International Auto Show (NAIAS), also known as the Detroit Auto Show, is an annual auto show held in Detroit, Michigan, U.S., at Huntington Place. The show was held in January from 1989 to 2019. It was intended to move to the summer in 2020, but was canceled due to the COVID-19 pandemic that year and 2021, before returning in September 2022. It is among the largest auto shows in North America. UPI says the show is "regarded as the foremost venue for [car] manufacturers to unveil new products".
