Karl Leonhard Reinhold (/ˈrnhld/; Austrian German: [ˈraɪnhɔld]; 26 October 1757 – 10 April 1823) was an Austrian philosopher who helped to popularise the work of Immanuel Kant in the late 18th century. His "elementary philosophy" (Elementarphilosophie) also influenced German idealism, notably Johann Gottlieb Fichte, as a critical system grounded in a fundamental first principle.

He was the father of Ernst Christian Gottlieb Reinhold (1793–1855), also a philosopher.
