The FIS Nordic World Ski Championships 1970 took place 14–22 February 1970 in Vysoké Tatry, Czechoslovakia (present-day Slovakia). This was the second time this city hosted the event having done so in 1935. It was the first time an event was televised in colour from Czechoslovakia though broadcasting there remained in black and white. This was the first championships that timed the results in hundredths of a second, a practice that continued until the 1980 Winter Olympics in Lake Placid when Sweden's Thomas Wassberg edged out Finland's Juha Mieto by 0.01 seconds in the men's 15 km event.
