Yeduguri Sandinti Rajasekhara Reddy (8 July 1949 – 2 September 2009), popularly known as YSR, was the Chief Minister of the Indian state of Andhra Pradesh. He represented the Indian National Congress party. He was elected to the 9th, 10th, 11th and 12th Lok Sabha from the Kadapa constituency for four terms and to the Andhra Pradesh Assembly for five terms from the Pulivendula constituency. He also holds the record of not losing any election throughout his political career.

In 2003 he undertook a three-month-long paadayaatra, or walking tour, across several districts in Andhra Pradesh. He led his party to victory in the next general and assembly elections held in 2004. On 2 September 2009, a helicopter carrying Reddy went missing in the Nallamala forest area. On the morning of 3 September 2009, media agencies reported that the helicopter had been found crashed on top of Rudrakonda Hill, 40 nautical miles from Kurnool. This was later confirmed by the Prime Minister's office and all five people aboard were pronounced dead at the scene.
