Raja Venkatappa Nayaka IV or Nalvadi lakshya (?–1858), was a prominent final ruler from the Nayak Dynasty of Shorapur (or Surapur) in present-day Yadgiri district of Karnataka state.

He refused to accept the suzerainty of the British East India Company and waged a war against them during the Indian Rebellion of 1857.

The British appointed Philip Meadows Taylor, a writer, as its Resident and Regent when the ruler there died, leaving a young prince[5] Venkatappa.

Two agents trying to sow seeds of dissension in the Belgaum army had been identified on 2 February 1858, and they were dispatched by Venkatappa and Raja of Jamkhandi.

Vagangeri Bhimrao from Surapur, a secret agent of the British, advised Venkatappa to go to Hyderabad and seek help from Salar Jung.

When Taylor met him, Venkatappa told him that: he did not wish to live and if he was to be sentenced to death, he must not be hanged like a criminal, but killed at the mouth of a cannon.
