At the 2015 FIFA Women's World Cup in Canada, Williams scored a 38th-minute penalty kick against Colombia, as England won 2–1 in Montreal on 17 June. In the semi-final in Edmonton on 2 July, Williams converted her second penalty of the tournament, in the 40th minute, to give England an equaliser against defending champions Japan. England lost the game 2–1. Two days later, and back in Edmonton, Williams scored another penalty, on this occasion in extra time, to give England the winning goal in a 1–0 victory over Germany. Her crucial goal gave England their first ever win over Germany and secured a bronze medal, the team's best ever finish at the FIFA Women's World Cup.
