The VG engine is a family of V6 engines designed and produced by Nissan between 1983 and 2004.

Nissan's and Japan's first mass-produced V6, the iron block/aluminum head 60° VG engine was produced in displacements between 2.0 and 3.3 liters. Early versions used SOHC cylinder heads with two valves per cylinder; later models featured DOHC cylinder heads, four valves per cylinder, a slightly different engine block and N-VCT, Nissan's own version of variable valve timing, delivering a smoother idle and more torque at low to medium engine speeds.

Both production blocks and head castings were used successfully in the Nissan GTP ZX-Turbo and NPT-90 race cars which won the IMSA GT Championship three years in a row.
