The Nissan 300ZX is a sports car that was produced across two different generations. As with all other versions of the Z, the 300ZX was sold within the Japanese domestic market under the name Fairlady Z.

It was sold in Japan from 1983 to 2000 and in the United States from 1984 to 1996, the 300ZX name followed the numerical convention initiated with the original Z car, the Nissan Fairlady Z (S30), which was marketed in the U.S. as the 240Z. The addition of the "X" to the car's name was a carryover from its predecessor, the 280ZX, to signify the presence of more luxury and comfort oriented features. The first generation 300ZX known as the Z31 model was produced from 1983 through 1989 and was a sales success becoming the highest volume Z-car for Nissan.
