A temperature regulating beverage container lid is provided. The device has a lid with a top surface, at least one annular sidewall, and an internal wall defining a drinking chamber and a ventilation chamber. The perimeter of the sidewall of the lid can secure over the brim of a beverage container. The drinking chamber has a floor and a drinking spout, the drinking spout in fluid communication with a tubular member. The tubular member, in turn, is in fluid communication with an aperture in the floor. The tubular member is surrounded by a material with a high thermal capacity. An aperture in the top surface of the lid provides ventilation while the ventilation chamber is sized to receive the drinking spout of an identical temperature regulating beverage container lid.
