Jerdon's nightjar is a medium-sized nightjar species native to southern India and Sri Lanka. Formerly considered as a subspecies of the long-tailed nightjar, it is best recognized by its distinctive call which sounds like a wooden plank being beaten periodically with each note ending in a quaver. The common name commemorates Thomas C. Jerdon who described the species.

Thomas Caverhill Jerdon was an English physician, zoologist and botanist. He was a pioneering ornithologist who described numerous species of birds in India. Several species of plants and birds including Jerdon's baza, Jerdon's leafbird, Jerdon's bushlark, Jerdon's nightjar, Jerdon's courser, Jerdon's babbler and Jerdon's bush chat are named after him.
