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 city of the region of Lombardy and of the province of Milan. The city proper has a population of about 1.3 million, while its urban area, roughly coinciding with its administrative province and the bordering Province of Monza and Brianza (created in 2004 splitting the northern part from the province of Milan itself), is one of Europe's largest with an estimated population of over 4 million spread over 1,980 km² (764.48 sq mi), with a consequent population density of more than 2,000 inhabitants/km². The growth of many suburbs and satellite settlements around the city proper following the great economic boom of the 1950s–60s and massive commuting flows suggest that socioeconomic linkages have expanded well beyond the boundaries of the city proper and its agglomeration, creating a metropolitan area of 7.4 million population expanded all over the central section of Lombardy region. 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.
