A ventilated toilet seat assembly for evacuating noxious odors from within a toilet bowl. The ventilated toilet seat defines an external channel on the lower surface thereof between a pair of concentric risers, including an innermost riser and an outermost riser, each being configured to form a seal along the surface of the toilet bowl when the ventilated toilet seat is lowered into engagement therewith. The external channel is configured to open within the toilet bowl to establish fluid communication from within the toilet bowl to the external channel. An outlet is defined between the external channel and a hinge assembly, which includes a hinge post for mounting the ventilated toilet sea t to a conventional toilet. The hinge post defines an internal conduit for evacuating the air within the toilet to an external location. The ventilated toilet sea t may include a toilet seat upper and a riser plate secured thereto and which defines the concentric risers on the bottom surface thereof.
