The '''Voskhod rocket''' ({{lang-ru|Восход}}, ''"ascent"'', ''"dawn"'') was a derivative of the [[Soviet Union|Soviet]] [[R-7 Semyorka|R-7]] [[ICBM]] designed for the [[human spaceflight]] [[Voskhod programme|programme]] but later used for launching [[Zenit (satellite)|Zenit]] [[reconnaissance satellite]]s.<ref>{{cite book|last1=Barensky|first1=C.

In 1966, all R-7 variants were equipped with the uprated core stage and strap-ons of the Soyuz [[11A511]].
All 11A57s launched after 1965 were functionally an 11A511 without the Soyuz's [[payload shroud]] and [[launch escape system]]. Around 300 were flown from Baikonur and Plesetsk through 1977 (various payloads, but Zenith PHOTINT satellites were the most common) when the newer 11A511U core was adopted.
