Sanguszko Park in Tarnów, Historical park in Tarnów, Poland

Sanguszko Park is a green space surrounding Sanguszko Palace in Tarnów, Poland, covering gentle slopes planted with both native and introduced tree species such as tulip trees and plane trees. The grounds are divided into a formally arranged southern section and a more open northern area with meadows.

The park's origins date to the late 18th century, when a Baroque-Classicist garden was created south of the Sanguszko Palace. In 1829 Wincenty Balicki described a garden "in Dutch taste", and the Italian-style garden in the south-west, the circular drive and exotic trees such as the maple-leaved plane and American tulip tree probably date from this period. In 1947 the palace-park complex passed to the State Treasury and was given to the Tarnów horticultural school; the stables were demolished and the irrigation canals partly filled, drying up the park ponds.

The two-level Italian garden below the palace was probably laid out in the 1820s, when Wincenty Balicki described the grounds as being in the Dutch taste; it was altered in the modernist style in the 1930s. Its central fountain was restored in 2020. The garden's name comes from its Italianate form, not from any Italian designer recorded in the sources.

The park lies in the Gumniska district of south-eastern Tarnów, bounded by Braci Saków and Sanguszków streets to the north and east and by the Strusinka stream to the south. Paths run across the palace hill, and the Italian garden with its fountain sits on the southern slope below the palace. The south-western part is wooded, and the steps in the park were renovated in 2016.

The plane tree in front of the palace, a nature monument, is probably the tree with the largest trunk circumference in Tarnów. The park's southern part holds the warmest spot in Poland. In the 1980s a rose garden was created on a small terrace of the warm slope.
