Dietrich Ritter Kralik von Meyrswalden (15 August 1884 – 27 December 1959) was an Austrian philologist who specialized in Germanic studies.

Kralik became Member of the Austrian Academy of Sciences in 1935, where he served as Head of the Dictionary Commission and Secretary of the Philosophical-Historical Class.

A member of the Nazi Party, Kralik was fired from the University of Vienna after the end of World War II.

He was, like many other Nazi collaborators and party members, rehabilitated in 1949, and subsequently reappointed a professor at the University, eventually even becoming Head of the Institute for Germanic Studies.

Kralik retired from his university duties in 1955, and was subsequently appointed an honorary professor.
