Tutankhamun (, Ancient Egyptian: twt-n-jmn), Egyptological pronunciation Tutankhamen () (c. 1341 c. 1323 BC), commonly referred to as King Tut, was an Egyptian pharaoh who was the last of his royal family to rule during the end of the 18th Dynasty (ruled c. 1332 1323 BC in the conventional chronology) during the New Kingdom of Egyptian history. His father is believed to be the pharaoh Akhenaten, identified as the mummy found in the tomb KV55. His mother is his father's sister, identified through DNA testing as an unknown mummy referred to as "The Younger Lady" who was found in KV35.Tutankhamun took the throne at eight or nine years of age under the unprecedented viziership of his eventual successor, Ay, to whom he may have been related. He married his paternal half-sister Ankhesenamun. During their marriage they lost two daughters, one at 56 months of pregnancy and the other shortly after birth at full-term. His namesTutankhaten and Tutankhamunare thought to mean "Living image of Aten" and "Living image of Amun", with Aten replaced by Amun after Akhenaten's death. A small number of Egyptologists, including Battiscombe Gunn, believe the translation may be incorrect and closer to "The-life-of-Aten-is-pleasing" or, as Professor Gerhard Fecht believes, reads as "One-perfect-of-life-is-Aten".Tutankhamun restored the Ancient Egyptian religion after its dissolution by his father, enriched and endowed the priestly orders of two important cults, and began restoring old monuments damaged during the previous Amarna period. He reburied his father's remains in the Valley of the Kings and relocated the capital from Akhetaten back to Thebes. Tutankhamun was physically disabled with a deformity of his left foot along with bone necrosis that required the use of a cane, several of which were found in his tomb. He had other health issues including scoliosis and had contracted several strains of malaria.The 1922 discovery by Howard Carter of Tutankhamun's nearly intact tomb, in excavations funded by Lord Carnarvon, received worldwide press coverage. With over 5,000 artifacts, it sparked a renewed public interest in ancient Egypt, for which Tutankhamun's mask, now in the Egyptian Museum, remains a popular symbol. The deaths of a few involved in the discovery of Tutankhamun's mummy have been popularly attributed to the curse of the pharaohs. Some of his treasure has traveled worldwide with unprecedented response; the Egyptian Supreme Council of Antiquities allowed tours beginning in 1961. He has, since the discovery of his intact tomb, been referred to colloquially as "King Tut".

Egypt (Arabic: مِصر, romanized: Miṣr), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip (Palestine) and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast, whose maximum width is 24 km (15 mi), separates Egypt from Jordan and Saudi Arabia. Cairo is the country's capital and largest city.

Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes, Karnak, and the Valley of the Kings, reflect this legacy and remain a significant focus of scientific and popular interest. Egypt's long and rich cultural heritage is an integral part of its national identity, which reflects its unique transcontinental location being simultaneously Mediterranean, Middle Eastern and North African. Egypt was an early and important centre of Christianity, but was largely Islamised in the seventh century and remains a predominantly Muslim country, albeit with a significant Christian minority.

Modern Egypt dates back to 1922, when it gained independence from the British Empire as a monarchy. Following the 1952 revolution, Egypt declared itself a republic, and in 1958 it merged with Syria to form the United Arab Republic, which dissolved in 1961. Throughout the second half of the 20th century, Egypt endured social and religious strife and political instability, fighting several armed conflicts with Israel in 1948, 1956, 1967 and 1973, and occupying the Gaza Strip intermittently until 1967. In 1978, Egypt signed the Camp David Accords, officially withdrawing from the Gaza Strip and recognising Israel. The country continues to face challenges, from political unrest, including the recent 2011 revolution and its aftermath, to terrorism and economic underdevelopment. Egypt's current government, a semi-presidential republic led by Abdel Fattah el-Sisi, has been described by a number of watchdogs as authoritarian or heading an authoritarian regime, responsible for perpetuating the country's problematic human rights record.

Islam is the official religion of Egypt and Arabic is its official language. With over 100 million inhabitants, Egypt is the most populous country in North Africa, the Middle East, and the Arab world, the third-most populous in Africa (after Nigeria and Ethiopia), and the fourteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres (15,000 sq mi), where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt's territory, are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

Egypt is considered to be a regional power in North Africa, the Middle East and the Muslim world, and a middle power worldwide. It is a developing country, ranking 116th on the Human Development Index. It has a diversified economy, which is the second-largest in Africa, the 33rd-largest economy by nominal GDP, and the 20th-largest globally by PPP. Egypt is a founding member of the United Nations, the Non-Aligned Movement, the Arab League, the African Union, Organisation of Islamic Cooperation and the World Youth Forum.
