Parco Lambro, Urban park in Municipio 3, Milan, Italy.

Parco Lambro is a park in Milan's Municipio 3, northeast of the city and bordering Segrate, crossed by the Lambro River that traces its layout. Its roughly 4 km of avenues pass two children's play areas, a skateboard ramp nicknamed Lambrooklyn, football pitches and a free rugby field named after Cesare Ghezzi. Five cascine stand within it, including San Gregorio Vecchio, still a working farm.

Parco Lambro was laid out to a design by Enrico Casiraghi, who set out to reproduce a summary of the Lombard landscape: a hill with two small lakes, a plain crossed by the Lambro and by irrigation channels, and woods of oaks, white hornbeams and willows. Many trees were cut for firewood during the war and later replanted without selection. From 1974 to 1976 the park hosted the three editions of the Festival del proletariato giovanile organised by the magazine Re Nudo.

The park's name comes from the Lambro River, which crosses it and shapes its layout. In 1974, 1975 and 1976 it hosted the three editions of the Festival del proletariato giovanile, organised by the magazine Re Nudo, the main Italian musical and countercultural event of the time; a live album, Parco Lambro, was recorded at the last edition. The skateboard area is nicknamed Lambrooklyn.

The park's avenues run over four kilometres, and part of them carries ordinary traffic, which is partly restricted on public holidays. There are two equipped children's play areas, a skateboard track and football pitches. Since 12 April 2014 it has had Italy's first free, open-access rugby field, named after Cesare Ghezzi.

The skateboard area is nicknamed Lambrooklyn, a local play on the name of New York's Brooklyn borough. The park also has Milan's first free, open-access rugby pitch, named after Cesare Ghezzi and inaugurated on 12 April 2014 by mayor Giuliano Pisapia.
