The Province of Milan (Italian: Provincia di Milano) is a province in the Lombardy region, Italy. Its capital is the city of Milan. The provincial territory is highly urbanized, resulting in the third highest population density among the Italian provinces with more than 2,000 inhabitants/km², just behind the provinces of Naples and the bordering Monza e Brianza, created in 2004 splitting the eastern part from the province of Milan itself.

This is a list of comuni (municipalities) with a population of over 30,000.

Milan (Western Lombard language: [miˈlan]; Italian: Milano [miˈlaːno] ( listen)) is the second-largest city in Italy and the capital of Lombardy as well as of the province of Milan. The city proper has a population of about 1.3 million, while its urban area is the 5th largest in EU and the largest in Italy with an estimated population of over 4.3 million. The growth of many suburbs and satellite settlements around the city proper following the economic miracle of 1950s–60s and massive commuting flows suggest that socioeconomic linkages have expanded well beyond the boundaries of its administrative limits and its agglomeration, creating a metropolitan area of 7.4 million population expanded all over the central section of Italy . It has been suggested that the Milan metropolitan area is part of the so-called Blue Banana, the area of Europe with the highest population and industrial density.

Milan was founded by the Insubres, a Celtic people. The city was later captured by the Romans in 222 BC, and later was the capital of the Western Roman Empire from 286 until 402 AD. Milan became one of the most prosperous Italian cities during the High Middle Ages, playing a primary role in the Lombard League. Later Milan became the capital of the Duchy of Milan, being ruled by the Visconti, the Sforza, the Spanish and the Austrians. In 1796, Milan was conquered by the French troops of Napoleon, only to be given again to the Austrian Empire at the Congress of Vienna of 1815. In 1859 the city was eventually annexed to the House of Savoy, and soon started to lead the industrialization process of the new Kingdom of Italy. During World War II, the city was badly affected by Allied bombings, and after German occupation in 1943, Milan became the main center of the Italian resistance movement. In post-war years, Milan enjoyed a prolonged economic boom, attracting large flows of immigrants from Southern Italy. During the past three decades, the city has seen a dramatic rise in the number of international migrants, and today 15.2% of Milan's population is foreign born.
