The Tata Nano was a compact city car manufactured and marketed by Indian automaker Tata Motors over a single generation, primarily in India, as an inexpensive rear-engined hatchback intended to appeal to current riders of motorcycles and scooters — with a launch price of one lakh rupees or US$2500 in the year 2008.

Numerous factors led to the decline of sales volume, including delays during the factory relocation from Singur to Sanand, early instances of the Nano catching fire, the perception of the car being unsafe and lacking quality due to cost cutting. Tata Motors projected production of 250,000 annually at launch, actually achieving sales in of 7591 for model year 2016-17. The project lost money for Tata, confirmed by former Tata Sons chairman Cyrus Mistry and confirmed by current Tata Motors management.

In 2017, Tata Motors said manufacture would continue due to the Tata's emotional commitment to the project, despite poor market demand. In 2018, Cyrus Mistry, Former Chairmen of the Tata Group, called the Tata Nano a failed project, with production ending in May 2018.
