日产Sentra (Nissan Sentra) 是日产汽车自1982年起至今销售的四门轿车。推出时因车型大小被归类为超小型车，2000年份车款增大后为小型车，2007年份车款再度增大为中型车。2006年以前Sentra车名主要用在日本以外市场的日产Sunny，但2007年起随着车型增大成为日产Sylphy的日本外名称，Sentra名称不曾在日本市场使用。在多个南美市场的日产Sunny也以Sentra名称销售。第一至三代Sentra在墨西哥市场以Nissan Tsuru (日语「鹤」) 为名销售，其中第三代B13自1992年至今仍在墨西哥以此名组装销售，与新版Sentra同时在墨西哥市场销售。

The Nissan Sentra is a car produced by Nissan since 1982. Originally subcompact in classification, for model year 2000 it was reclassified as a compact car, becoming mid-size for 2007. 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 Nissan Sylphy. The Sentra nameplate is not used in Japan. Many other countries in South 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 (Japanese for crane), and the B13 model is still sold under that name, alongside the updated models badged as Sentra.
