Abstract–A catalog of the meteorite collection hosted by the National Museum of Natural Sciences of Madrid is presented. It includes 88 stony meteorites, 56 iron meteorites, and 13 stony-iron meteorites, as well as 14 tektites. The National Museum of Natural Sciences of Madrid (MNCN) holds the most important meteorite collection in Spain. This collection was first organized by the Marquis of Socorro, during the second half of the nineteenth century (1866–1882), based on several specimens stored in the museum, and several later exchanges and acquisitions. In 1886, according to Fernández Navarro (1923), the collection included 68 specimens corresponding to 64 meteorites (falls or finds). When the geologist Salvador Calderón became the head of the mineralogy section of the museum (1901–1910), meteorites began to receive special attention and there was a significant increase in the number of specimens thanks to exchanges wit
