The invention discloses a herringbone ladder. The herringbone ladder comprises a first ladder body (1) and a second ladder body (2) which are connected on the top; long connecting rods (3) are symmetrically arranged at the two sides of the first ladder body (1); short connecting rods (4) are symmetrically arranged at the two sides of the second ladder body (2); an elongated slot (5) is formed in the long connecting rod (3); a plurality of overhead hooks (6) are arranged at the bottom of the elongated slot (5); and a locating piece (7) is arranged at the end of the short connecting rod (4), can slide in the elongated slot (5) and can be clamped in the overhead hook (6). The two ladder bodies are pushed open and fixed by clamping the locating pieces in the overhead hooks, and the height of the whole ladder can be appropriately changed by clamping the locating pieces in the different overhead hooks.
