The hallux, big toe, or great toe is the innermost toe of the foot, counted as digit I.

In humans, the hallux is longer than the second or pointer toe for a majority of people. The human big toe has limited grasping ability.

In foot fetishism, the hallux is commonly the toe that is sucked, kissed, licked, and/or tickled.
