The invention discloses a herringbone ladder. The herringbone ladder comprises a top plate, two vertical ladders and a fixing rod, wherein the two vertical ladders are symmetrically arranged; each vertical ladder comprises two opposite ladder beams and a plurality of rungs between the two ladder beams; top ends of the ladder beams are rotationally arranged at two ends of the top plate; braking trundles are arranged at bottom ends of the ladder beams; the fixing rod is a telescopic rod, one end of the telescopic rod is fixed in the center of the lower surface of the top plate, and a base is arranged at the other end of the telescopic rod. Accordingly, the herringbone ladder can be prevented from turning on one side when used, the safety of a user is improved, the herringbone ladder is convenient to move, time and labor are saved, and the height of the herringbone ladder can be adjusted according to actual conditions.
