No, the Andes Mountains do not run through Brazil. The Andes are primarily located along the western coast of South America, stretching through countries such as Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
While Brazil is home to many mountain ranges, including the Serra do Mar and Serra da Mantiqueira, the Andes do not extend into Brazilian territory. The geographical boundaries of the Andes are well-defined, with the range following a north-south axis that is parallel to the Pacific Ocean, distinctly separate from the vast Brazilian Highlands to the east.
