Saint Petersburg (Russian: Санкт-Петербург, tr. Sankt-Peterburg; IPA: [sant pʲɪtʲɪrˈburk] ( listen)) is a city and a federal subject (a federal city) of Russia located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. In 1914 the name of the city was changed to Petrograd (Russian: Петроград; IPA: [pʲɪtrɐˈgrat]), in 1924 to Leningrad (Russian: Ленинград; IPA: [lʲɪnʲɪnˈgrat]), and in 1991, back to Saint Petersburg.
In Russian literature, informal documents, and discourse, the "Saint" (Санкт-) is usually omitted, leaving Petersburg (Петербург, Peterburg). In common parlance Russians may drop "-burg" (-бург) as well, referring to it as Peter (Питер, Russian: [ˈpʲitʲɪr]).
