An acoustic wave filter includes series arm resonators and parallel arm resonators each including an acoustic wave resonator including an IDT electrode including a pair of comb-shaped electrodes each including electrode fingers and a busbar electrode. An electrode finger connected to neither of the busbar electrodes of the pair of comb-shaped electrodes is a floating withdrawal electrode, and of all the electrode fingers of the pair of comb-shaped electrodes, the electrode finger that is connected to a same busbar electrode to which the electrode fingers on both sides thereof are connected is a polarity-reversing withdrawal electrode, and, of the series arm resonators, the series arm resonator having a lowest anti-resonant frequency includes an IDT electrode including the floating withdrawal electrodes, and the series arm resonator includes an IDT electrode including the polarity-reversing withdrawal electrodes.
