Abstract: The study aimed to determine the importance of ethnobotany in the province of Pacasmayo, La Libertad, Peru, in 2022. Semi-structured interviews were conducted with 95 villagers over 20 years of age, collecting information on 73 useful plant species, distributed in 66 genera and 34 families, with Asteraceae, Fabaceae, Poaceae and Solanaceae being the most representative.
