A thermal pizza slice container apparatus for transporting a pizza slice and maintaining temperature includes a base having a base bottom side, a base sidewall, and an open base top side defining a base cavity. The base bottom side is sector-shaped and configured to accommodate a slice of pizza. A bottom lip is coupled to a perimeter of the open base top side. A lid has a lid top side, a lid sidewall, and an open lid bottom side defining a lid cavity. The lid top side is sector-shaped and conforms to the base bottom side. The lid sidewall has a flared lower portion that is selectively engageable with the bottom lip to seal and alternatively unseal the base cavity and the lid cavity. The base and the lid are each comprised of an outer shell layer and an inner insulation layer.
