The VAZ-2106 is an automobile which was produced by Russian manufacturer AvtoVAZ. It was in production from 1978 to 2001. A development of the VAZ-2103, the 2106 was a four-door, four-seat saloon powered by a 78 hp (58 kW; 79 PS) 1,570 cc (96 cu in) single overhead cam inline four engine of Lada's own design. It used the pistons of the VAZ-21011's 1,294 cc (79.0 cu in) and the crankshaft of the VAZ-2103's 1,570 cc (96 cu in). Though not more powerful than the 2103's engine, it produced more torque, 86 ft•lbf (117 N•m) rather than 76 ft•lbf (103 N•m), making it easier to drive. Top speed was 93 mph (150 km/h), with 0–62 mph (0–100 km/h) acceleration in 16 seconds.

It was also known as the Zhiguli 2106 and as the Lada 1600. The 2106 was "the top of the Eastern Bloc charts for comfort and prestige", since the ZiL and GAZ-M20 Pobeda were out of reach for most motorists. It debuted in December 1975, and "would become the most popular and most numerous VAZ product". It differed in detail from the 2103, having black plastic headlight surrounds and grille, instead of chrome, and larger taillights.

The 21061, with the 75 hp (56 kW; 76 PS) 1,452 cc (88.6 cu in) VAZ-2103 engine, and 21063, with the 64 hp (48 kW; 65 PS) 1,294 cc (79.0 cu in), appeared in 1979. (The 21063 would disappear in 1993.) The less-powerful, but also cheaper, 21061 would be the sales leader, helping make the 2106 the top Lada-branded marque.
