The Dushdi Mala Medal is a civil decoration in the honours system of Thailand, and the highest-ranked medal among those granted for services to the state. The award was established by King Chulalongkorn in 1882 to celebrate the centennial of the Rattanakosin Kingdom. Originally given in five categories, each with an associated pin attached as a medal bar, today it is only awarded for distinguished services in the domains of the arts and sciences, which is denoted by the Pin of Arts and Science.

State decorations awarded by Thai King take the form of orders and medals. This page lists them by order of precedence.
