Abstract: A trash bag support apparatus includes a flexible and unitary body being selectively adaptable between linear and arcuate positions for removably inserting into a trash bag and engaging with an inner surface thereof. The body has opposed end portions and a top portion integral therewith. A plurality of elongated leg portions having lower edge portions are integrally disposed with the top portion and extend downwardly therefrom for defining a plurality of channels therebetween. The edge portions define a uniform line of weakness below which the trash bag is unsupported by the apparatus.
