"Reveille" called in French "Le Réveil" is a bugle call, trumpet call, drum, fife-and-drum or pipes call most often associated with the military; it is chiefly used to wake military personnel at sunrise. The name comes from réveille (or réveil), the French word for "wake up".

The tunes used in the Commonwealth of Nations are different from the one used in the United States, but they are used in analogous ways: to ceremonially start the day. British Army Cavalry and Royal Horse Artillery regiments sound a call different from the infantry versions, known as "The Rouse" but often misnamed "Reveille", while most Scottish Regiments of the British Army sound a pipes call of the same name, to the tune of "Hey, Johnnie Cope, Are Ye Waking Yet?", a tune that commemorates the Battle of Prestonpans. For the Black Watch, since the Crimean War, '"Johnnie Cope has been part of a sequence of pipe tunes played at an extended reveille on the 15th of every month known as "Crimean Long Reveille".

In modern times, the U.S. military plays (or sounds) "Reveille" in the morning, generally near sunrise, though its exact time varies from base to base. On U.S. Army posts and Air Force bases, "Reveille" is played by itself or followed by the bugle call "To the Colors" at which time the national flag is raised and all U.S. military personnel outdoors are required to come to attention and present a salute in uniform, either to the flag or in the direction of the music if the flag is not visible. While in formation, soldiers are brought to the position of parade rest while "Reveille" plays then called to attention and present arms as the national flag is raised. On board U.S. NavyMarine Corps, and Coast Guard facilities, Reveille is generally sounded separately from morning colors. Reveille is sounded at an earlier time such as 0600 (6 am), and then the flag is generally raised at 0800 (8 am) while "The Star-Spangled Banner" or the bugle call "To the Colors" is played. On some U.S. military bases, "Reveille" is accompanied by a cannon shot.

In Commonwealth Remembrance Day and Remembrance Sunday services, and ANZAC Day services, "Last Post" begins the period of silent reflection, and "Reveille" ends it. The two tunes symbolize sunset and sunrise respectively, and therefore, death and resurrection. ("Reveille" is often replaced by "The Rouse", a bugle call commonly mistaken for "Reveille", although these are actually two different tunes.) Winston Churchill had "Last Post" sounded at his funeral, followed by "Reveille", as did Prince Philip, Duke of Edinburgh

"To Reveille" or "to sound Reveille" is often used among military personnel as a term meaning "to notify personnel that it is time to wake up", whether the bugle call is actually sounded or not. Units lacking the personnel or equipment necessary to play the tune will often assign the duty to "sound Reveille" to the last watch of the night, who must ensure that others are roused at the proper time, by any appropriate means (often by actually shouting the word reveille until everyone is awake).
