Vostok 5 (Russian: Восток-5, Orient 5 or East 5) was a joint mission of the Soviet space program together with Vostok 6; as with the previous pair of Vostok 3 and Vostok 4 the two Vostok spacecraft came close to one another in orbit and established a radio link.

Cosmonaut Valery Bykovsky was originally intended to stay in orbit for eight days, but the mission details changed many times due to elevated levels of solar flare activity at the time and he was eventually ordered back after five days. This remains the record for solo manned flight in Earth orbit.

A problem with the spacecraft's waste collection system is reported to have made conditions "unpleasant" in the capsule. The only other difficulty encountered was that, like on Vostok 1 and Vostok 2, the re-entry module failed to separate cleanly from the service module when it was time for Bykovsky to come home.

The Vostok 5 landing coordinates were 53°23′52″N 67°36′18″E / 53.39777°N 67.60500°E / 53.39777; 67.60500, 2 km northwest of Karatal, North Kazakhstan, Kazakhstan; and 550 km northwest of Karagandy, Kazakhstan. At the landing location is a small fenced park with two monuments. One monument is a 10-meter tall silver rectangle with a small stone marker nearby listing the date of the landing. The second monument is an L-shaped sandy colored stone structure. One leg of the "L" is an observation deck with stairs leading to it. The other leg of the "L" has a space-themed mural carved into the stone face. The mural depicts a floating cosmonaut in a spacesuit surrounded by stars, telescopes, planets, and the Sun.[3][4][5]

The re-entry capsule is on display at the Tsiolkovsky Museum in Kaluga.
