Museo de Filatelia de Oaxaca, Stamp museum in Oaxaca, Mexico.

The Museo de Filatelia de Oaxaca is a stamp museum in central Oaxaca displaying thousands of stamps, postal documents, and related objects across multiple galleries within a modern building. The collection includes specialized holdings of cancellations, envelopes, and miniature sheets that document postal history through both artistic and scientific perspectives.

The museum was founded in 1998 through the initiative of philanthropist Alfredo Harp Helú and documents the evolution of Mexican postal communication. The collection grew from a vision to show how postal practices changed in Mexico over time.

The museum's name is often shortened to MUFI, and its José Lorenzo Cossío y Cosío library is devoted entirely to philately. Visitors can also see a postal art room and a philatelic club, spaces that show stamp collecting as a living practice rather than only a historical display.

The museum is located at Reforma 504 in downtown Oaxaca and is easy to reach on foot from other central locations. Visitors should plan for several hours to walk through the galleries at a comfortable pace.

The museum preserves rare series of cancellation types showing how different regions of Mexico marked their mail. These details reveal stories about local post offices and regional differences that visitors would otherwise never discover.
