Datsun was a Japanese automobile manufacturer brand owned by Nissan. Datsun's original production run began in 1931. From 1958 to 1986, only vehicles exported by Nissan were identified as Datsun. Nissan phased out the Datsun brand in March 1986, but relaunched it in June 2013 as the brand for low-cost vehicles manufactured for emerging markets. Nissan considered phasing out the Datsun brand for a second time in 2019 and 2020, eventually discontinuing the struggling brand in April 2022.
