A collapsible smoke reducing fire pit comprises a combustion barrel with an open end and a base end, a locking lid with ash screen, an insulated ash container with heat shield, a folding leg assembly, and a component mount for items such as an attachable grill. The collapsible smoke reducing fire pit is designed to be portable and collapsible with the insulated ash container and folding leg assembly being able to fit inside the combustion barrel for storage and transportation. It is further designed to promote efficient combustion, reduce and prevent the ejection of embers, provide for the efficient collection and disposal of ashes, and conduct heat in such a way so as to prevent burning of objects around and beneath the fire pit.
