The 1986 Speedway World Team Cup was the 27th edition of the FIM Speedway World Team Cup to determine the team world champions. A new format was started in 1986 whereby teams were seeded into groups, with Group 1 containing the leading nations competing over three legs to determine the champions. A promotion and relegation system was in place for the groups. Denmark won all three legs and therefore easily won their fourth consecutive title (and sixth in total) equalling Sweden's six titles and moving into equal second place in the all time list. It was also Hans Nielsen's sixth gold medal having taken part in all of Denmark's title wins.
