The national flag of Egypt (علم مصر [ˈʕælæm mɑsˤɾ]) is a tricolour consisting of the three equal horizontal red, white, and black bands of the Egyptian revolutionary flag dating back to the 1952 Egyptian Revolution. The flag bears Egypt's national emblem, the Egyptian eagle of Saladin centered in the white band.

The Egyptian Free Officers who toppled King Farouk in the Revolution of 1952 assigned specific symbolism to each of the three bands of the revolutionary and liberation flag. The red band symbolizes the Egyptians’ blood in the war against colonization. The white band symbolizes the purity of the Egyptians’ heart. The black band below the white, symbolizes the manner in which darkness is overcome.

Egypt's Revolutionary and Liberation flag was then an inspiration to several Arab countries and was adopted by many Arab states. The same horizontal tricolour is used by Iraq, Syria, Sudan, and Yemen (and formerly Libya), the only difference being the presence (or absence) of distinguishing national emblems in the white band.

The development of the modern Egyptian flag was determined first by the Muhammad Ali Dynasty, under whom Egypt was united with Sudan, and later by the rise of Egyptian nationalism and revolutionary ideas among the Egyptian Army.
