The 1990 England rugby union tour of Argentina was a series of matches played in July and August 1990 in Argentina by the England national rugby union team. It was the second tour of Argentina by England and was apparently arranged without the tour manager Geoff Cooke's knowledge and at an inconvenient time of the year for the England players in July and August. For this reason, eight England players declined the invitation to make the trip, and the only seasoned internationals on the tour were Will Carling, Richard Hill, Wade Dooley, Brian Moore, Jeff Probyn and Peter Winterbottom.
It was also notable in that it was the first series between Argentina and a Home Nation since 1981, as the Home Nations were prohibited from playing Argentina in the aftermath of the Falklands War in 1982 and represented a start of a warming period of relations between the United Kingdom and Argentina.
