Caldo verdé (Portuguese for green broth) is a popular soup in Portuguese cuisine. The basic traditional ingredients for the broth are potatoes, collard greens or kale, olive oil and salt. Additionally garlic or onion may be added. Some recipes add meat, making it similar to Italo-American wedding soup. The dish is usually accompanied by slices of paio (traditional sausage of Portugal and Brazil), and with Portuguese cornbread for dipping. In Portugal, caldo verdé is typically consumed during Portuguese celebrations, such as weddings, birthdays and popular celebrations, for example, the St. John festival. It is sometimes consumed before the main course meal or as a late supper.

Caldo verdé originated from the Minho Province in northern Portugal. Today, it is a traditional national favourite that has spread across the nation and abroad, especially to places where a large community of Portuguese immigrants has settled such as Brazil, Massachusetts, New Jersey, and Rhode Island.
