Thulium is a chemical element; it has symbol Tm and atomic number 69. It is the thirteenth element in the lanthanide series of metals. It is the second-least abundant lanthanide in the Earth's crust, after radioactively unstable promethium. It is an easily workable metal with a bright silvery-gray luster.

Natural thulium in ceramic magnetic materials is used in microwave equipment and is useful for doping fibre lasers. Once used for bombarding in a nuclear reactor, thulium could be employed as a radiation source in portable X-ray equipment. Unlike the other lanthanides, thulium has a low-to-moderate acute toxic rating.
