The present invention relates to an outdoor cookware lid comprising a suction handle and, more specifically, to an outdoor cookware lid comprising a suction handle and being capable of volume minimization, when carried, by comprising the handle, which is easily detachable and attached by the suction force of a suction plate, and having the effects of: allowing the handle to be detached/coupled in a suction manner and thus allowing volume minimization, since there is no protruding handle as the handle is detached during storage; allowing volume minimization by carrying only one handle, since the one handle can be used with multiple lids; being stably disposed, with the handle detached, when turned over and used as a dish and having a fine appearance; removing any risk of burns during detachment as the handle is detached in a manner in which the suction force is removed by pressing a protrusion at the top of the handle; allowing convenient detachment, since the handle can be easily detached with a little force; and allowing the handle to be coupled quickly and easily in a manner in which the handle is disposed at the center of a circular plate, then pressed, and instantly adhered.
