Via Laietana (Catalan pronunciation: [ˈbi.ə ləjəˈtanə]) is a major street in Barcelona, Catalonia, Spain, in the Ciutat Vella district.

Via Laietana was named after the Laietani, an Iberian people who inhabited the region around Barcelona, Maresme, Vallès, and Baix Llobregat.

The construction of Via Laietana was first projected in 1879 and started in 1907, with the aim of communicating Eixample with the waterfront, amid much controversy due to the required demolition of a large number of houses and the removal of the streets in the area.

As some of the traditional guilds of the city, some dating back to the Middle Ages, were located there, they had to be relocated in different parts of Barri Gòtic, notably Plaça de Sant Felip Neri.

The first section to be built was named Carrer de Bilbao, which nowadays is a separate, shorter street that stems from the larger Via Laietana.
