The 20th arrondissement of Paris (known in French as the XX arrondissement de Paris or simply as "le vingtième") is the last of the consecutively numbered arrondissements of the capital city of France. Also known as Ménilmontant (pronounced [menilmɔ̃tɑ̃]) after the Ménilmontant neighbourhood it encompasses in its northwest, it is on the right bank of the River Seine and contains some of the city's most cosmopolitan districts. It covers four quarters: Belleville, Saint-Fargeau, Père-Lachaise and Charonne. In 2019, it had a population of 194,994.

The 20th arrondissement is internationally best known for its Père Lachaise Cemetery, the world's most-visited cemetery where one can find the tombs of a number of famous people.

The land area of this arrondissement is 5.984 km (2.310 sq mi; 1,479 acres).

The population of Paris's 20th arrondissement peaked in 1936, when it had 208,115 inhabitants. Today it remains very dense in population and business activity with 197,067 inhabitants in 2009 and 54,786 jobs as of the last census in 1999.

Place of birth of residents of the 20th arrondissement in 1999

This group is made up largely of former French settlers, such as pieds-noirs in Northwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), as well as to a lesser extent foreign-born children of French expatriates. A foreign country is understood as a country not part of France in 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics. An immigrant is a person born in a foreign country not having French citizenship at birth. An immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.
