2020 end-of-year rugby union internationals

The 2020 end of year rugby union tests, also referred to as the 2020 Autumn internationals in the Northern Hemisphere, were a number of rugby union test matches contested during the months of October, November and December 2020, primarily involving countries from the Northern Hemisphere hosting those from the Southern Hemisphere. Also involved in matches were those from second-tier teams. These international games counted towards World Rugby's ranking system, with a team typically playing from two to four matches during this period.

Due to the COVID-19 pandemic causing a delay or cancellation of many nations' scheduled matches, a different format was developed for this year. The Autumn Nations Cup, an eight-team tournament involving England, Fiji, France, Georgia, Ireland, Italy, Scotland and Wales, replaced the cancelled matches. Also as a result of the pandemic, this year's fixtures incorporated postponed matches from the 2020 Six Nations Championship and 2020 Rugby Europe Championship, the 2020 South American Rugby Championship and all matches from the 2020 Tri Nations Series.
