The 2017–18 Ashes series (named Magellan Ashes Series for sponsorship reasons) was a series of Test cricket matches contested between England and Australia for The Ashes. The series was played at five venues across Australia between 23 November 2017 and 8 January 2018. England were the defending holders of the Ashes going into the series, having won in 2015. Australia won the series 4–0, regaining The Ashes after taking an unassailable lead with an innings victory in the third Test.
