The Mazda Sentia is a mid-size rear wheel drive luxury car that was sold by Mazda in Japan from 1991 to 1999 over two generations. It replaced the Mazda Luce nameplate on the Mazda H platform, and continued the tradition of being Mazda's largest flagship sedan, which had been in production since the late 1960s.

The Mazda Luce is an executive car that was produced by Mazda in Japan from 1966 until 1991. It was widely exported as the Mazda 929 from 1973 to 1991 as Mazda's largest sedan. Later generations were installed with luxury items and interiors as the Luce became the flagship offering. The Luce was replaced by the Sentia in 1991 which was also exported under the 929 nameplate.
