He told reporters after a cabinet meeting that it was unanimously decided to name the new capital Amaravati.
The new capital is being built in Vijayawada-Guntur region and Amaravati, the ancient town on the banks of the Krishna river, is part of the region.
Naidu said the new capital would have the strength of both the ‘vastu’ and auspicious name.
Amaravati was home to the Satavahana dynasty 2,000 years ago. It is famous for Buddhist sites including a stupa built during Emperor Ashoka’s time.
Naidu, who also briefed the cabinet about his visit to Singapore, said Singapore had come forward to build the capital.
He said the master plan for the first phase of the capital would be ready by May 15.
The chief minister announced that the new capital would be linked with radial roads.
He said a 200-km-long ring road will be built connecting the new capital with Vijayawada and Guntur.
