Elimar Klebs (15 October 1852 – 16 May 1918) was a German historian of ancient history. He was the brother of Georg Klebs.

Klebs was born in Braunsberg (Braniewo), Prussia. He studied in Berlin under Theodor Mommsen and Heinrich von Treitschke, receiving his doctorate in 1876 and his habilitation in 1883. He also worked as a Privatdozent in Berlin. Along with Hermann Dessau and Paul von Rohden, he was involved in producing the first edition of the Prussian Academy of Sciences' "Prosopographia Imperii Romani". Klebs prepared the first volume, letters A-C, which appeared in 1897. From the winter semester of 1906, he was a professor for Ancient History at the University of Marburg. Because of a serious illness, he was put on leave in 1913 and discharged from his academic duties the following year. He died in Marburg.

Klebs focused on Ancient Roman history, including the "Historia Augusta", the "Historia Apollonii", and Petronius. He also contributed to the "Realencyclopädie der Classischen Altertumswissenschaft".
