A list of men and women international rugby league matches played throughout 2020 and does not include wheelchair rugby league international matches.
A † denotes a recognised, but unofficial match that did not contribute to the IRL World Rankings.
Many fixtures scheduled were cancelled or rescheduled due to the ongoing COVID-19 pandemic.
The Kangaroo tour of England, Oceania Cup, and European Championship were all cancelled.
As a result of the travel restrictions from COVID-19, only two respective men's and women's test matches were played in 2020; a men's international between Peru and Brazil in Sydney before the pandemic began, the Griffin Cup match between Germany and Netherlands, and a women's 'Clash of the Pacific' double-header in Auckland where Tonga and Niue, and New Zealand and Tonga played each other.
