A vehicle sound absorption structure has: a recessed cell that has an opening on one end of the cell; a divider that is provided within the cell and that divides an acoustic wave entering the cell from the opening into two acoustic waves; reflectors that reflect one of the two acoustic waves divided at the divider and reflect the other acoustic wave respectively toward the opening, and that generate a phase difference between the one acoustic wave and the other acoustic wave; and an interfering portion that is provided within the cell and that causes the one acoustic wave and the other acoustic wave, which have been respectively reflected at the reflectors, to interfere with each other.
