A cenotaph is an empty tomb or a monument erected in honour of a person or group of people whose remains are elsewhere. It can also be the initial tomb for a person who has since been reinterred elsewhere. Although the vast majority of cenotaphs honour individuals, many noted cenotaphs are instead dedicated to the memories of groups of individuals, such as the lost soldiers of a country or of an empire.
The English word "cenotaph" derives from the Greek: κενοτάφιον kenotaphion (κενός kenos, meaning "empty", and τάφος taphos, "tomb"—from θαπτω thapto, I bury).
Cenotaphs were common in the ancient world. Many were built in Ancient Egypt, Ancient Greece and across Northern Europe (in the shape of Neolithic barrows).
The cenotaph in Whitehall, London—designed in 1919 by Sir Edwin Lutyens—influenced the design of many other war memorials in Britain and in the British sectors of the Western Front, as well as those in other Commonwealth nations. Lutyens' cenotaph was chosen as a deliberately secular monument.

Located on the edge of St George's Park in Rink Street, it was designed by Elizabeth Gardner to commemorate the men who died in the First World War (1914–1918) and was erected by the monumental mason firm of Pennachini Bros. On either side of the central sarcophagus are statues by Technical College Art School principal, James Gardner, who served in the trenches during the war. One depicts St George and the Dragon, the other depicts the sanctity of family life. Surrounding the sarcophagus are a number of bas-relief panels depicting scenes and people during the First World War. It was unveiled by Mrs W F Savage and dedicated by Canon Mayo on 10 November 1929. A surrounding memorial wall commemorates the men and women killed during World War II.

A monument which has come to be known to as the "Cenotaph" was erected in Plaza San Martín, in downtown Buenos Aires, to commemorate the Argentinian soldiers who died during the Falklands War, in 1982. The monument consists of a series of plaques of black marble with the names of the fallen, surrounding a flame, and during the day is guarded by two soldiers.

In the Falkland Islands, there are several war memorials to commemorate those killed in the Falklands War in 1982. The main memorial for Falkland Islanders is the 1982 Liberation Memorial, a cenotaph erected in Stanley in 1984 which lists all the British Army regiments, RAF squadrons, Royal Navy vessels and the Royal Marine formations and units that took part in the conflict. The names of the 255 British military personnel who died during the war are listed on ten plaques behind the Memorial, divided into the service branches.
Services are held at the Memorial each year on 14 June (Liberation Day) and on Remembrance Sunday, with wreaths being laid at the foot of the Memorial.

A cenotaph in the UK that stands in Whitehall, London, was designed by Sir Edwin Lutyens and replaced Lutyens' identical wood-and-plaster cenotaph erected in 1919 for the Allied Victory Parade, and is a Grade I listed building. It is undecorated save for a carved wreath on each end and the words "The Glorious Dead", chosen by Lloyd George. It was intended to commemorate specifically the victims of the First World War, but is used to commemorate all of the dead in all wars in which British servicemen and women have fought. The dates of the First World War and the Second World War are inscribed on it in Roman numerals. The design was used in the construction of many other war memorials throughout the British Empire.

Although most notable cenotaphs commemorate notable individuals buried elsewhere, many cenotaphs pay tribute to people whose remains have never been located, particularly those lost at sea. Some such cenotaphs are dedicated to victims of the RMS Titanic whose bodies were not recovered after the sinking. Although Isidor Straus's body was recovered, Ida Straus's body was not, and a cenotaph at the Straus Mausoleum at Woodlawn Cemetery in the Bronx is dedicated to Isidor and Ida together. Its inscription reads: "Many waters cannot quench love—neither can the floods drown it." (Song of Solomon 8:7) The striking cenotaph of Major Archibald Butt, aide to U.S. President William Taft, is located at Arlington National Cemetery.
In Inishmore, one of the Aran Islands of Ireland, drowning was formerly such a common cause of death for island fishermen that each family had a memorial to those lost at sea known as leachtaí cuimhneacháin (memorial cairns). Most were erected in the 19th century, although some date back to the eighteenth. A modern memorial was erected in 1997.
Main article: Chhatri
In India, cenotaphs are a basic element of Hindu architecture, later used by Moghuls as seen in most of the mausoleums of Mughal Emperors which have two burial chambers, the upper one with a cenotaph, as in Humayun's Tomb, Delhi, or the Taj Mahal, Agra, while the real tomb often lies exactly below it, or further removed. The term chhatri, used for these canopylike structures, comes from Hindustani word literally meaning umbrella, and are found throughout the northwestern region of Rajasthan as well as in Madhya Pradesh and Maharashtra. In the Shekhawati region of Rajasthan, chhatris are built on the cremation sites of wealthy or distinguished individuals. Chhatris in Shekhawati may consist of a simple structure of one dome raised by four pillars to a building containing many domes and a basement with several rooms. In some places, the interior of the chhatri is painted in the same manner as the Haveli.
Cenotaphs have also been the subject of a number of illustrations including:
In the Internet age, virtual cenotaphs are common in the game World of Warcraft, as well as in The Elder Scrolls series games though modding add-ons. 
They have also been created in the augmented reality game Ingress in honour of the slain MIT police officer Sean Collier and in memory of the victims of the 1942 Struma disaster.
On 13 January 2016, Belgian amateur astronomers at MIRA Public Observatory dedicated, in conjunction with radio station Studio Brussels, an asterism of seven stars in the vicinity of Mars which had been photographed at the exact time of David Bowie's death; when appropriately connected they form the iconic lightning bolt of Aladdin Sane.
