The Land Rover Discovery, also commonly known as the "Disco", is a series of medium to large premium SUVs, produced under the Land Rover marque, from the British manufacturer Land Rover, and later Jaguar Land Rover. The series is currently in its fifth iteration (or generation, according to the manufacturer), the first of which was introduced in 1989, making the Discovery the first new model series since the launch of the 1970 Range Rover – on which it was based – and only the third new product line since the conception of the Land Rover (vehicle and brand) by Rover in 1948. The model is sometimes called influential, as one of the first to market a true off-road capable family car.

Although the Range Rover had originally been designed as an everyday four wheel drive car that could be used as both a utility vehicle and a family car, it had progressively moved upmarket through its life to evolve into a luxury vehicle sold at a much higher price point. The Discovery was intended to fulfill the role the Range Rover originally was intended for; a segment which was now dominated by Japanese rivals such as the Nissan Patrol, Mitsubishi Pajero and Toyota Land Cruiser. Although positioned below the Range Rover in the company's line-up, the vehicle was both longer and higher, offered more room in the back, and optionally also more seats. Space utilization became more sophisticated in later iterations, but the series keeps offering seats for seven occupants. Despite originally being sold as an affordable alternative to the Range Rover, the Discovery has also progressively moved upmarket through its successive generations to become a bonafide luxury SUV.
