A foldable cart frame has a folding mechanism, a connecting seat, two rear legs, and a handle unit. The folding mechanism has a base seat, at least one guiding rod connected to the base seat, a sliding seat slidably disposed on the at least one guiding rod, and a linkage assembly moveably connected to the sliding seat. The connecting seat is movably disposed on the folding mechanism. The two rear legs are disposed on the base seat. The handle unit is moveably inserted through the base seat, is fixedly connected to the sliding seat, and can drive the sliding seat and the connecting seat to move. The two rear legs are driven by the linkage assembly. The foldable cart frame can be folded and expanded conveniently and quickly. The connecting seat and its connecting components can form a stable supporting structure after expanding.
