In the 2006–07 season, although still in a part of Harlequins' Academy side, he was capped by the
England Saxons in the first two matches of the year. Brown got selected for the
2007 England rugby union tour of South Africa. Unaffected by a severe incidence of food poisoning within the England camp, Brown picked up his first full England cap in the record 58–10 defeat to South Africa. Brown was called into the England Saxons side that defeated
Ireland A on 1 February 2008. On 1 June 2008, he started for England against the Barbarians at Twickenham in an uncapped match. On 14 June 2008, he started for England in their 37–20 defeat to New Zealand. Brown vied with
Ben Foden for the England full-back spot in 2012, coming off the bench in the victory over Scotland at Murrayfield. He spent the
2013 Six Nations playing on the left wing with
Alex Goode taking the number 15 jersey. He was finally picked at fullback by
Stuart Lancaster and was subsequently named England's Man of the Series following his form during the 2013 Autumn Internationals. Brown scored his first try for England in the
2014 Six Nations Championship match against France on 1 February 2014 and his second came a week later in a comprehensive 20–0 victory against Scotland. He then scored two tries and was named Man of the Match for the third time in the tournament in the 52–11 away win over Italy in Rome. In recognition of Brown's form throughout the
2014 Six Nations Championship, he was selected by the general public for the 2014 RBS Six Nations player of the championship award. Brown was an integral part of the
England team that won the RBS
Six Nations Championship in 2016 and played every match in the 3–0 series win over
Australia. Brown was named Man of the Match in the England vs Wales' Six Nations game on 10 February 2018.
