Phillumeny (also known as Phillumenism) is the hobby of collecting different match-related items: matchboxes, matchbox labels, matchbooks, matchcovers, matchsafes, etc.

The word, derived from Greek phil- [loving] + Latin lumen- [light], was introduced by the British collector Marjorie S. Evans in 1943 (who later became president of the British Matchbox Label & Booklet Society, now renamed as the British Matchbox Label and Bookmatch Society). A person who engages in phillumeny is a phillumenist.

Collecting of matchbox labels emerged together with matches. In some collections it is possible to find labels from chemical matches, produced in 1810 - 1815 long before the modern matches arrived. Quite often people who went abroad brought back matchboxes as souvenirs from other countries. After World War II a lot of match factories worked in close contact with local phillumenists, issuing special non-advertising sets. The hobby became especially widespread from the 1960s through the 1980s. Widespread introduction of bulky (for collectors) cardboard matchboxes with less distinct images on them, much poorer quality of print and, also some social phenomena, made this hobby (like many others, not connected with commerce) much less engaged.
