Egyptian temples were built for the official worship of the gods and in commemoration of the pharaohs in ancient Egypt and regions under Egyptian control. Temples were seen as houses for the gods or kings to whom they were dedicated. Within them, the Egyptians performed the central rituals of Egyptian religion: giving offerings to the gods, reenacting their mythology through festivals, and warding off the forces of chaos. These rituals were seen as necessary for the gods to continue to uphold maat, the divine order of the universe. Caring for the gods was the obligations of pharaohs, who dedicated prodigious resources to temple construction and maintenance. Pharaohs delegated most of their ritual duties to priests, but most of the populace was excluded from direct participation in ceremonies and forbidden to enter a temple's most sacred areas. Nevertheless, a temple was an important religious site for all classes of Egyptians, who went there to pray, give offerings, and seek oracular guidance.

The most important part of the temple was the sanctuary, which typically contained a cult image of its god. The rooms outside the sanctuary grew larger and more elaborate over time, so that temples evolved from small shrines in late Prehistoric Egypt (late fourth millennium BC) to large stone edifices in the New Kingdom (c. 1550–1070 BC) and later. These edifices are among the largest and most enduring examples of ancient Egyptian architecture, with their elements arranged and decorated according to complex religious symbolism. Their typical layout comprised a series of enclosed halls, open courts, and entrance pylons aligned along the path used for festival processions. Beyond the temple proper was an outer wall enclosing secondary buildings.

A large temple owned sizable tracts of land and employed thousands of laymen to supply its needs. Temples were therefore key economic as well as religious centers. The priests who managed these powerful institutions wielded considerable influence, and despite their ostensible subordination to the king, they may have posed significant challenges to his authority.

Temple-building in Egypt continued despite the nation's decline and ultimate loss of independence to the Roman Empire in 30 BC. With the coming of Christianity, traditional Egyptian religion faced increasing persecution, and temple cults died out during the fourth through sixth centuries AD. The buildings suffered centuries of destruction and neglect. At the start of the nineteenth century, a wave of interest in ancient Egypt swept Europe, giving rise to the discipline of Egyptology and drawing increasing numbers of visitors to the civilization's remains. Dozens of temples survive, and some have become world-famous tourist attractions that contribute significantly to the modern Egyptian economy. Egyptologists continue to study the surviving temples and the remains of destroyed ones for information about ancient Egyptian society.

Ancient Egyptian temples were meant as places for the gods to reside on earth. Indeed, the term the Egyptians most commonly used to describe the temple building, ḥwt-nṯr, means "mansion (or enclosure) of a god". A divine presence in the temple linked the human and divine realms and allowed humans to interact with the god through ritual. These rituals, it was believed, sustained the god and allowed it to continue to play its proper role in nature. They were therefore a key part of the maintenance of maat, the ideal order of nature and of human society in Egyptian belief. Maintaining maat was the entire purpose of Egyptian religion, and it was the purpose of a temple as well.

Because he was credited with divine power himself, the pharaoh, as a sacred king, was regarded as Egypt's representative to the gods and its most important upholder of maat. Thus, it was theoretically his duty to perform the temple rites. While it is uncertain how often he participated in ceremonies, the existence of temples across Egypt made it impossible for him to do so in all cases, and most of the time these duties were delegated to priests. The pharaoh was nevertheless obligated to maintain, provide for, and expand the temples throughout his realm.

Although the pharaoh delegated his authority, the performance of temple rituals was still an official duty, restricted to high-ranking priests. The participation of the general populace in most ceremonies was prohibited. Much of the lay religious activity in Egypt instead took place in private and community shrines, separate from official temples. As the primary link between the human and divine realms, temples attracted considerable veneration from ordinary Egyptians.

Each temple had a principal deity, and most were dedicated to other gods as well. Not all deities had temples dedicated to them. Many demons and household gods were involved primarily in magical or private religious practice, with little or no presence in temple ceremonies. There were also other gods who had significant roles in the cosmos but, for unclear reasons, were not honored with temples of their own. Of those gods who did have temples of their own, many were venerated mainly in certain areas of Egypt, though many gods with a strong local tie were also important across the nation. Even deities whose worship spanned the country were strongly associated with the cities where their chief temples were located. In Egyptian creation myths, the first temple originated as a shelter for a god—which god it was varied according to the city—that stood on the mound of land where the process of creation began. Each temple in Egypt, therefore, was equated with this original temple and with the site of creation itself. As the primordial home of the god and the mythological location of the city's founding, the temple was seen as the hub of the region, from which the city's patron god ruled over it.
