Ernst Immanuel Bekker (16 August 1827 in Berlin – 29 June 1916 in Heidelberg) was a German jurist and professor.

Bekker studied law at Heidelberg, where he was a member of the Corps Saxo-Borussia.^[1] In 1853 he gained his Habilitation at the Martin-Luther-Universität Halle-Wittenberg in Roman law. He was extraordinary professor there from 1855 until he was called to an ordinary professorship at Greifswald in 1857. In 1874 he finally returned to Heidelberg. In 1886, he became Pro-Rector of the University of Heidelberg, and became emeritus in 1908. He remained in Heidelberg until his death.

Besides work on Roman law Bekker principally wrote philosophical treatises and works on natural science.
