The present invention relates to an outdoor cookware lid including a suction handle, and more particularly, to an outdoor cookware lid including a suction handle that is easily attachable using a suction plate and easily detachable to reduce the volume of the outdoor cookware lid when carrying the outdoor cookware lid. The suction handle is detachable from the outdoor cookware lid to reduce the volume of the outdoor cookware lid when storing the outdoor cookware lid. The suction handle may be used with other lids, thereby reducing the volume of lids when carrying lids. When the outdoor cookware lid is flipped and used as a dish, the suction handle may be detached from the outdoor cookware lid so as to stably place the outdoor cookware lid and improve the appearance of the outdoor cookware lid. The suction handle may be easily detached from the outdoor cookware lid in a simple manner by pressing a head provided on an upper side of the suction handle to remove adhesive force, thereby preventing a user from being burned. The suction handle may be easily attached to the outdoor cookware lid in a simple manner by placing the suction handle on a center portion of a circular plate and pressing the suction handle.
