The European section of the 2018 FIFA World Cup qualification acted as qualifiers for the 2018 FIFA World Cup, which is being held in Russia, for national teams which are members of the Union of European Football Associations (UEFA). Apart from Russia, who qualified automatically as hosts, a total of 13 slots in the final tournament were available for UEFA teams.
The qualifying format was confirmed by the UEFA Executive Committee meeting on 22–23 March 2015 in Vienna.
The qualification process started on 4 September 2016, almost two months after UEFA Euro 2016, and ended on 14 November 2017. Belgium, England, France, Germany, Iceland (for the first time), Poland, Portugal, Serbia, and Spain qualified in the first round by winning their groups. Croatia, Denmark, Sweden and Switzerland qualified by winning their playoffs.
Four-time champions Italy missed out on qualification for the first time since 1958 after losing in the playoffs to Sweden, while the Netherlands failed to qualify for the tournament for the first time since 2002 after finishing third in 2014, and second in 2010. Iceland, with 335,000 inhabitants, became the smallest country ever to qualify for the World Cup finals.
