List of dual-code rugby internationals

A dual-code rugby international is a rugby footballer who has played at the senior international level in both codes of rugby, 13-a-side rugby league and 15-a-side rugby union. Rugby league started as a breakaway version of rugby in Northern England in 1895 and in New Zealand and Australia in 1908, and consequently a number of early top-class rugby league players had been star players in the rugby union code.
