An anti-spill funnel assembly which includes an outer reservoir funnel having a center funnel positioned therein. The outer reservoir funnel includes a cone-shaped portion having a spout extending downwardly therefrom. The center funnel includes a cone-shaped portion having a hollow stem extending downwardly therefrom. This center funnel also includes a spout extending downwardly from the lower end of the cone-shaped portion thereof. The hollow stem portion has a plurality of vertically disposed slots formed therein. When the funnel assembly is being used to fill a container or a piece of equipment, the spouts of the reservoir funnel and center funnel are inserted downwardly into the fill opening of a container or equipment. As liquid is poured into the container or equipment, any overflow liquid is passed upwardly into the outer reservoir funnel to prevent a spill.
