The WKW Tor (Thorium) or previously WKW Wilk (Wolf) is a modern anti-materiel and/or sniper rifle produced in Poland by the Zakłady Mechaniczne Tarnów. The abbreviation "WKW" stands for Wielkokalibrowy Karabin Wyborowy or Large Caliber Sniper Rifle. The rifle was initially given the working name Wilk, but after completion of development it was given the final name Tor. This rifle was developed between 2000 and 2004 and the first selected units in the Polish army apparently received Tor rifles in around 2005 onwards.

The WKW Tor makes use of a manually operated rotary bolt action weapon of bull-pup layout. It is fed from detachable box magazines and is fitted with a folding and adjustable bipod and an adjustable rear monopod. Standard sighting equipment is a Schmidt & Bender X3−12 P/MII telescope sight which is placed on Picatinny rails above the receiver.
