Zinovi Petrovich Rozhdestvenski (1848-1909) was an admiral of the Russian Imperial Navy, who was involved in the Russo-Japanese War.

Prior to the war against Japan, Rozhdestvenski was commander of the Baltic Fleet. He was then ordered to take his fleet to East Asia. In the Battle of Tsushima (1905) his fleet was almost entirely destroyed. In 1906 his case was taken to court, where he pleaded guilty of losing the battle.
