The 70 Series is a family of Toyota Land Cruiser models produced since 1984. It replaced the 25-year-old 40 Series as the off-road model of the Land Cruiser lineup, while the contemporary 60 Series developed into more comfortable luxury SUVs starting with the 80 Series. Despite major changes in styling and numerous technological updates, the 70 Series was designed to retain the off-road capabilities and durability associated with the 40 Series.

The pickup version was designated the Toyota 300 Series Land Cruisers For Sale, the Troop Carrier became the 78 series, and the short-wheelbase version was phased out in most markets. The principal mechanical changes were: coil spring (instead of leaf spring) live front axle; longer rear leaf springs; 5-bolt wheels instead of 6-bolt wheels; redesigned steering wheel; redesigned front indicators; and, in the cab-chassis, a longer wheelbase, which increased the rear storage capacity.
