A ladder standoff device adapted to be readily attached to and detached from a ladder comprises an elongated axle member having a pair of wheels rotatably mounted at opposing ends thereof, an elongated standoff bar attached to the axle member and extending transverse thereto, and a handle member pivotally attached to the end of the standoff bar remote from the axle member. The standoff device is attached to a rung of the ladder by a pivot structure that is mounted on the standoff bar and consists of a fixed hook member and a cooperating sleeve that is slideable along the standoff bar; and the standoff device may be locked in position by a further attachment member that is slideable along the handle member and adapted to engage a rung of the ladder different from the rung upon which the device pivots. The axle member and standoff bar may each be of telescopic construction to permit adjustment of the distance between the wheels that engage a wall structure adjacent the ladder, and the distance between the axle member and the rung of the ladder upon which the device is pivotally mounted.
