A corn stalk guide system for reducing or eliminating the loss of corn stalks as they are guided into the grab rolls of a corn header. The corn stalk guide system generally includes a pair of guide members which may be positioned on opposing teeth of a corn header assembly to guide corn stalks into the assembly without being expelled by exposed sprockets. Each guide member is a tapered, plastic structure having a plurality of apertures extending therethrough. The first guide member will be secured to a first tooth via one or more fasteners extending through the one or more apertures and the second guide member will be secured to a second tooth similarly with fastener(s) and aperture(s). Each guide member will cover a sprocket which normally would extend out from the tooth, thus guiding corn stalks and preventing loss of corn stalks.
