Experiments in the Revival of Organisms (Russian: О́пыты по оживле́нию органи́зма) is a 1940 documentary film directed by David Yashin that purports to document Soviet research into the resuscitation of clinically dead organisms. The English version of the film begins with British scientist J. B. S. Haldane giving an introduction.

The operations in the film, as well as the design of the heart-lung machine demonstrated in it, the autojektor, were done by Sergei Brukhonenko, whose work is said to have led to the first operations on heart valves. While the experiments shown are generally considered to have taken place, the legitimacy of the film itself is controversial.
