The condiment package opening device is a cutting tool. The condiment package opening device is configured for use with a soft-sided condiment package. The soft-sided condiment package is typically a sealed single serving package containing an edible substance that is intended: 1) to enhance the flavor of a food; and, 2) to be applied to the food after the food has been prepared for consumption but before the food is consumed. Typical condiments include, but are not limited to, mustard and ketchup. The condiment package opening device forms an opening in the soft-sided condiment package such that the condiment contained within the soft-sided condiment package may be removed through the formed opening. The condiment package opening device comprises a cutting mechanism and an optional housing.
