Yes. All you need is an oxidizer. For example, you could have a fire with fuel, an ignition source and chlorine gas. I would avoid that fire if I were you, by the way

A fire cannot exist without oxygen. There are elements such as magnesium which will burn without oxygen, but that is not considered fire. A fire requires oxygen.
