The Walker Chronicle, which is sometimes called Chronicle 25, is one of the historiographical texts from ancient Babylonia. It deals with events during the reign of the kings of the Kassite Dynasty and the Second Dynasty of Isin, and contains several duplicate lines with the Eclectic Chronicle.
For a very brief introduction to the literary genre of chronicles, go here. The Walker Chronicle was published by C.B.F. Walker in G. van Driel e.a. (eds.): Zikir Šumim: Assyriological Studies Presented to F.R. Kraus on the Occasion of His Seventieth Birthday (1982). More information can be found in Jean-Jacques Glassner, Mesopotamian Chronicles (Atlanta, 2004).
