The WZ-111 heavy tank (Chinese: WZ-111重型坦克) was a heavy tank that was developed by the People's Republic of China (PRC) during the 1960s but was eventually cancelled in 1966 due to many mechanical problems.

The WZ-111 featured a 780 hp (580 kW) supercharged diesel engine and a torsion bar suspension system.

The idler wheels were in front with drive sprockets in the rear.

Many of the suspension components were the same type used in Soviet heavy tank designs such as the IS-2.

Because of many technological problems that surfaced during testing, the design was shelved around 1966.
