Count Hans Hermann Carl Ludwig von Berlepsch (29 July 1850 – 27 February 1915) was a German ornithologist who took an interest in the birds of South America.

This cousin had travelled to South America and was involved in bird conservation and he once sent back a French medal honoring the bird-collecting ornithologist for discovering a new hummingbird.

He was the first son of Karl von Berlepsch and his wife Johanna Margaretha Theodora who was the daughter of state-councillor Koch of Kassel.

He then used his inherited wealth to sponsor bird collectors in South America, including Jan Kalinowski, the Garlepps, and Hermann von Ihering.

Other ornithologists who visited included Jean Stolzmann, Ernst Hartert who worked for the collections, Ladislas Taczanowski, Paul Leverkuehn, and Friedrich Kutter.

He became a specialist on identifying the source of skins merely by examining the method and style of preparation and the handwriting on the labels.
