The FIS Nordic World Ski Championships 1966 took place 17–27 February 1966 in Oslo, Norway at the Holmenkollen ski arena. This was the third time the Norwegian capital hosted this event having done so in 1930 and at the 1952 Winter Olympics. This also equaled the most times a city had hosted with Lahti, Finland (1926, 1938, 1958) and Zakopane, Poland (1929, 1939, and 1962).
