Pearce made his debut for England against Brazil in a 1–1 friendly draw at Wembley on 19 May 1987 at age 25. Replacing Kenny Sansom as the first choice left-back for his country, injury prevented him from playing in the 1988 UEFA European Championship. Following the tournament, he was consistently picked as left-back and scored his first England goal in his 21st senior appearance for England on 25 April 1990, scoring in a 4–2 friendly win over Czechoslovakia at Wembley.
