The Nissan Sunny is an automobile built by the Japanese automaker Nissan from 1966 till 2004. In the early 1980s, the brand changed from Datsun to Nissan in line with other models by the company. Although production of the Sunny in Japan ended in 2004, the name remains in use in China and GCC countries for a rebadged version of the Nissan Almera.

The Nissan Sentra is a series of automobiles manufactured by the Japanese automaker Nissan since 1982. Since 1999, the Sentra has been categorized as a compact car, while previously it occupied the subcompact class. Until 2006, Sentra was a rebadged export version of the Japanese Nissan Sunny, but since the 2013 model year, Sentra is a rebadged export version of the Sylphy. The Sentra nameplate is not used in Japan. Many other countries in Latin America sell their versions of the Sunny as the Sentra. In Mexico, the first three generations of the Sentra were known as the Nissan Tsuru, and the B13 model was sold under that name until 2017, alongside the updated models badged as Sentra.
