In the buildup to the 2019 Six Nations Championship, Gatland said that should Wales start off the campaign with a victory over France, "we can win it given we have home games against England and Ireland." Down 0–16 after the first half in Paris, Wales rallied to win 24–19, and subsequent wins over Italy (26–15), England (21–13), Scotland (18–11) and Ireland (25–7) saw them win the Grand Slam, stretching their winning run to 14, breaking their previous record of 11 set in 1910, and making Gatland the first-ever coach to win three Grand Slams in the Five or Six Nations era.
