The VAZ-2106 Zhiguli (alternatively Zhiguli 2106) is a sedan produced by the Soviet (later Russian) automaker VAZ, In export markets, it was known simply as Lada 1600 or alternatively as Lada 2106. In the domestic market it was popularly nicknamed Шестёрка (Šestyorka, in English; The sixth one). A hugely popular car and one of most successful Lada models, it was in serial production for 30 years (from 1976 to 2006).

It debuted in December of 1975, and "would become the most popular and most numerous VAZ product". It externally differed from its predecessor, the VAZ-2103, firstly by having smaller grille due to having plastic headlight surrounds, different bumpers and by wider taillights also featuring reverse lights, which were then a new feature for VAZ models. Internally it was almost as same as its predecessor with only minimal differences; most notably by being the first VAZ model with height adjustable headrests on front seats and also by its steering wheel; it was visually easily recognizable by being decorated with classic Russian ornaments together with Lada logo on its central (leather) part. The VAZ-2106 was severely restyled in the second half of 1990s, its chrome lined elements were further reduced; the chrome external/side mirrors became black metallic back in the first half of 1980s when the VAZ-2103 was discontinued, however, the grille was now replaced with black plastic one, also featuring a new front Lada badge.
