The all-time medal table for all Olympic Games from 1896 to 2018, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.

This is a list of host cities of the Olympic Games, both summer and winter, since the modern Olympics began in 1896. Since then, summer and winter games have usually celebrated a four-year period known as an Olympiad; summer and winter games normally held in staggered even years. There have been 28 Summer Olympic Games held in 23 cities, and 23 Winter Olympic Games held in 20 cities. In addition, three summer and two winter editions of the Games were scheduled to take place but later cancelled due to war: Berlin (summer) in 1916; Tokyo–Helsinki (summer) and Sapporo–Garmisch-Partenkirchen (winter) in 1940; and London (summer) and Cortina (winter) in 1944. The 1906 Intercalated Olympics were officially sanctioned and held in Athens. However, in 1949, the International Olympic Committee (IOC), decided to unrecognize the 1906 Games. The 2020 Summer Olympics in Tokyo were postponed for the first time in the Olympics history to summer 2021 due to the COVID-19 pandemic with the 2022 Winter Olympics being held roughly six months later in Beijing.

The International Olympic Committee (IOC) uses three-letter abbreviation country codes to refer to each group of athletes that participate in the Olympic Games. Each geocode usually identifies a National Olympic Committee (NOC), but there are several codes that have been used for other instances in past Games, such as teams composed of athletes from multiple nations, or groups of athletes not formally representing any nation.

The tradition of carrying the Olympic flame from Olympia, Greece, the birthplace of the Ancient Olympic Games, to the host city of the modern Olympic Games via a torch relay was first introduced in 1936, ahead of the 1936 Summer Olympics.
