15th of May (Arabic: مدينة 15 مايو) is a new urban community and a satellite city of Cairo, Egypt, located to the south of it. Its cornerstone was laid in 1978 on an area of 6400 acres, which tripled to 18,000 acres by 2017. It was constructed to solve the problem of insufficient accommodation. However, after almost forty years, it had only 93,574 residents according to the 2017 census.

The name "15th of May City" was chosen to commemorate the Corrective Revolution (launched as the "Corrective Movement"), a reform program (officially just a change in policy) launched on 15 May 1971 by President Anwar Sadat. The revolution involved purging Nasserist officials and security forces deemed pro-Soviet and left-wing, while garnering popular support by framing the takeover as a continuation of the Egyptian Revolution of 1952. However, Sadat's Corrective Revolution also marked a significant shift in foreign policy, economy, and ideology, and included the imprisonment of political opponents in Egypt, including liberals and Islamists.
