A computer-implemented method for multipath load balancing may include (1) identifying a plurality of paths from a source switch to a destination switch, (2) determining, for each of the plurality of paths, a limiting bandwidth of the path based at least in part on the lowest link bandwidth of one or more data links in the path, and (3) balancing network traffic that is transmitted from the source switch to the destination switch across the plurality of paths based at least in part on the limiting bandwidth of each of the plurality of paths. Various other methods, systems, and computer-readable media are also disclosed.
