No, nearly all spacecraft use a mixture of liquid oxygen (LOX) as an oxidizer to help the fuel burn quickly and fiercely even in a vacuum. The fuel itself is usually either an alcohol/water mixture (good for low budget or smaller craft), or liquid hydrogen. There are also some more scenario-specific fuels, such as RP-1 (refined petroleum 1 and/or rocket propellant 1) which is used only for the first stage of the Saturn V.

The liquid oxygen and hydrogen can be refined from water through a process called electrolysis (I'm sure wiki has an article on it), so only petroleum based fuels have any danger of running out.
