FIS Ski Flying World Championships 1986

The FIS Ski Flying World Ski Championships 1986 were held March 8–9 in Bad Mitterndorf, Austria, which had previously hosted the championships in 1975.

It was the first time a nation won more than one medal at the same championships, with host nation Austria earning gold and silver in the event. For the second and final time, the championships were held in consecutive years (1972 and 1973 are the others). These championships have been held in even-numbered years since this one.
