A ladder assembly is disclosed that mounts to a truck tailgate. In one embodiment, the ladder assembly includes a base which is coupled to the tailgate. A pair of legs are slidably and pivotably mounted to the based and each pair of legs includes three segments that define upper, middle, and lower ladder sections. A first pair of joints hingedly couples the upper ladder section to the middle ladder section. A second pair of joints hingedly couples the middle ladder section to the lower ladder section. The first pair of joints is larger than the second pair of joints such that when the upper ladder section is folded into the middle ladder section a pocket is formed therebetween for receiving the lower ladder section.
