A combination outdoor fireplace and pizza oven system includes a main body with a framework assembly. The framework assembly has a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein. Each of the fireplace firebox and the oven firebox is in communication with the smokebox. The smokebox is in communication with the chimney flue. The framework assembly is covered by a refractory heat resistant mortar. The oven firebox is suspended above the fireplace firebox and is configured for baking pizza. The smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox.
