This article lists the national football team squads for the 1990 FIFA World Cup final tournament held in Italy, between 8 June and 8 July 1990.
Replacement of injured players was permitted during the tournament at the discretion of FIFA.
Two goalkeepers (for Argentina and England) were allowed to replace their injured counterparts under this ruling.
Number of caps counts until the start of the World Cup, including all pre-tournament friendlies.
Note: with the exception of the goalkeepers, who were assigned the traditional shirt numbers for the role (1, 12 and 22) the Italian team was numbered alphabetically within their respective positions: Defenders (from 2 to 8), Midfielders (from 9 to 14) and Forwards (from 15 to 21).
The exception to this was Goalkeeper Jim Leighton who was given the traditional number 1 jersey.
All the teams included 3 goalkeepers, except Colombia and Republic of Ireland who only called two.
