**Logic of Relatives (1870)**, more precisely, "Description of a Notation for the Logic of Relatives, Resulting from an Amplification of the Conceptions of Boole's Calculus of Logic", is a 60 page memoir by Charles Sanders Peirce, published in the *Memoirs of the American Academy of Arts and Sciences* in 1870. The paper is one of the wellsprings of contemporary systems of logic.

After a brief account of its historical setting, the body of this article traces the outlines of Peirce's 1870 Logic of Relatives, noting a few of its more striking anticipations, interpreting its formulations with respect to the contemporary understanding of logic that it served to shape, and setting in higher relief a few of its promises that have yet to be taken up.
