The National Democratic Party, often referred to in Egypt as simply the National Party, was the ruling political party in Egypt from 1978 to 2011. It was founded by President Anwar Sadat in 1978. The NDP wielded uncontested power in state politics, usually considered a de facto single party, with authoritarian characteristics, inside an officially multi-party system, from its creation until the resignation of Sadat's successor Hosni Mubarak in response to the Egyptian Revolution of 2011.

Muhammad Anwar es-Sadat was an Egyptian politician and military officer who served as the third president of Egypt, from 15 October 1970 until his assassination by fundamentalist army officers on 6 October 1981. Sadat was a senior member of the Free Officers who overthrew King Farouk in the Egyptian Revolution of 1952, and a close confidant of President Gamal Abdel Nasser, under whom he served as Vice President twice and whom he succeeded as president in 1970. In 1978, Sadat and Menachem Begin, Prime Minister of Israel, signed a peace treaty in cooperation with United States President Jimmy Carter, for which they were recognized with the Nobel Peace Prize.
