A safety platform for a ladder comprises a foot platform which engages a lower rung of the ladder and brackets for being secured to an upper rung of the ladder to support the platform. A locking means is provided on the foot platform for securely engaging a lower rung of the ladder to prevent movement of the foot platform. Arcuate elements which engage an upper rung of the ladder are provided with set screws for clamping them to the upper rung also to provide stability for the foot platform.
