Soyuz 14 (Russian: Союз 14, Union 14) was a 1974 manned spaceflight to the Salyut 3 space station. Soyuz 14 is also the name given to the Soyuz spacecraft which was used to bring the cosmonauts to and from the station. The mission was part of the Soviet Union's Almaz program to evaluate the military applications of human spaceflight. The mission's crew members were cosmonauts Yuri Artyukhin and Pavel Popovich. At the time, the military nature of this mission and the station itself were not acknowledged by Soviet authorities. The flight was the first successful mission to a space station by the Soviets. The mission proved to be the only one for Salyut 3 as Soyuz 15 failed to dock with the station in August and the station was de-orbited January 1975. With the American Skylab missions now complete, the flight marked the start of the monopoly of manned space activities by the Soviets until the 1981 launch of STS 1, the first space shuttle flight, save for the joint Apollo-Soyuz flight of 1975.

With the Salyut 3 space station successfully launched on 24 June 1974, Soyuz 14 was sent into orbit nine days later, on 3 July. The craft docked with the space station the next day, performing a manual approach for the last 100 metres. The crew tested the suitability of Salyut 3 as a manned military reconnaissance platform. They also tested Almaz station systems, such as the solar arrays.

Increased solar activity raised safety issues, but it was decided radiation levels were within safe limits, so the flight continued.
