The Oceanian section of the 2018 FIFA World Cup qualification acted as qualifiers for the 2018 FIFA World Cup, to be held in Russia, for national teams which are members of the Oceania Football Confederation (OFC). A total of 0.5 slots (i.e. 1 inter-confederation play-off slot) in the final tournament was available for OFC teams.
The 2016 edition of the OFC Nations Cup once again doubled as the second round of the OFC qualifying competition for the 2018 FIFA World Cup (similar to the 2012 OFC Nations Cup and the OFC qualifying competition for the 2014 FIFA World Cup). Unlike in 2012, however, the team that won the qualifying competition and advanced to the intercontinental play-off, New Zealand, was the same team that also won the OFC Nations Cup and represented the OFC at the 2017 FIFA Confederations Cup.
