The Liga Occidental de Béisbol Profesional (Western Professional Baseball League) was a baseball circuit that operated between 1954 and 1963 in Maracaibo, the capital city in the Venezuela state of Zulia. The league played their games at the old olympic stadium of Maracaibo. The LOBP started to operate as a four-team league on December 7, 1954, and was managed by local entrepreneurs under the guidance of George Trautman, an American baseball executive, who also helped the league to join organized baseball to become a professional baseball circuit.
