Calle Prat, Financial district street in Valparaíso, Chile.

Calle Prat runs from Plaza Sotomayor, continuing Calle Serrano, along the foot of Cerro Alegre and Cerro Concepción to Plazoleta Turri, where it meets Calle Cochrane and becomes Calle Esmeralda. Its buildings are examples of eclectic historicist architecture from the early 20th century, with uniform heights by sections and columns, cornices and pediments. Trolleybuses run along it.

The street began as a commercial hub in the 1830s when a luxury inn was established in this location. In the early 1900s, modern buildings like the Stock Exchange were constructed, reflecting the area's financial importance.

The street received its name in honor of Arturo Prat, a lawyer and naval officer who became a military hero during the Pacific War.

The street draws heavy foot traffic and is served by trolleybus routes that connect to the regional transport network. Watch for buses when crossing the street.

The Bolsa de Corredores building, inaugurated in 1915, was designed by Carlos Federico Claussen and Gustavo Jullian from plans by Anberd and Lacrote. Its glass dome lights the trading hall on the fifth floor. The earlier exchange was demolished to make way for the Monumento a los Héroes de Iquique.
