This is a list of the leaders for caps in rugby union test matches, with a minimum of 90 confirmed test caps. Unlike in cricket, where both countries must grant test status for a match to be considered a test, rugby union requires only one nation to recognise a match as a test in order for it to be included in test statistics for that nation. The British and Irish Lions and Pacific Islanders do not represent one specific nation, but are also considered test teams because they are selected by a group of recognised national unions. Some nations have sometimes granted test caps for matches against teams such as the invitational Barbarians side; these are included only if the player's nation actually granted a test cap for a particular match.
Players who are still active at international level, or who have not yet announced international retirement, are in bold. Players who are still active at club level but have either retired from international rugby or have not been selected for their national team for a year or more are in italics.
