Mazatlán is a city in the Mexican state of Sinaloa. The city serves as the municipal seat for the surrounding municipio, known as the Mazatlán Municipality. It is located on the Pacific coast across from the southernmost tip of the Baja California Peninsula. Mazatlán is a Nahuatl word for "place of deer". The city was colonized in 1531 by the Conquistador where many indigenous people lived. By the mid-19th century, a large group of immigrants arrived from Germany.
