Volfram je kemijski element koji u periodnom sustavu elemenata nosi simbol W, atomski (redni) broj mu je 74, a atomska masa mu iznosi 183.84(1).
Volfram također ima najviše vrelište od svih elemenata (5660°C) i najviše talište od svih kovina (3410°C), a zbog tog drudgog svojstva volframove niti koriste u žaruljama koje što se više zagrijavaju daju više svjetlosti.
