Parc de Sant Martí, Public park in Sant Martí district, Barcelona, Spain.

Parc de Sant Martí occupies two zones in Sant Martí de Provençals: a square plaza bounded by Carrer de Menorca, Huelva, Treball and Agricultura, a quarter of the grounds, with a paved basketball court, a bench area and a children's play area; and a larger irregular triangle with a lake, broad meadows of alders, aspens and Lombardy poplars, and a perimeter strip along Carrer de Menorca holding a football pitch, a market, a secondary school and the church of Sant Martí de Provençals.

The park was built in two phases, the first completed in 1985 and the second in 1992, following a project begun in 1979 by Nicolau Maria Rubió i Tudurí. After his death, architects Antonio Armesto, Carles Martí and Miquel Sodupe finished the work. The land belonged to Sant Martí de Provençals, a municipality annexed to Barcelona in 1897.

The parish church of Sant Martí de Provençals, dedicated to Martin of Tours, was rebuilt between the 15th and 17th centuries in Gothic style; its façade by Joan Aymerich shows interwoven flamboyant mouldings and a tympanum of the saint cutting his cloak. The bell tower, finished in 1688, is Baroque. The three farmhouses Ca l'Arnó, Can Planas and Can Cadena now serve as civic spaces: a play centre, a residential centre and an organic-farming research centre with an urban allotment and farm-animal pens.

The park is easy to reach from Carrer de Menorca and the L2-Sant Martí metro station is nearby. Several bus lines including H10, V29, and V31 serve the area for visitors arriving by public transport.

The three farmhouses are Ca l'Arnó, Can Planas and Can Cadena, each given a different civic use: a children's play centre, a residential centre and a centre for organic farming research with an urban allotment and pens of farm animals. The church beside them, Sant Martí de Provençals, has a flamboyant façade by Joan Aymerich and a bell tower finished in 1688.
