The reserve's director, Surendra Mahra, said the body of the big cat was found along the roadside at the Sarpduli range by a tourist.
The tourist was initially excited on having spotted a tiger, but on a closer look noticed that the animal was dead since the body was motionless with flies swarming all over.
The tourist then informed authorities who performed a postmortem of the animal.
The tiger was found to have a deep wound on its leg and the postmortem confirmed that it died of hunger as the animal's stomach was found empty. The tiger died as it could not hunt for prey, Mahra said.
According to a recent Wildlife Institute of India survey, the Corbett reserve has the highest population of tigers in India, with a count of 215.
