马脚蹄，通常称为马蹄，是马的脚部长出来的蹄，正如人体长出脚甲一样，用以保护马的脚部。

人工驯化的马匹，现多用作赛马用途。练马师为尽力保护马原生的马蹄，不让马儿因为长期奔跑而令马蹄受到损害。一般护理马蹄的方法有：

1. 为马蹄擦拭马蹄润肤膏
2. 在马脚蹄底部镶上马蹄铁，等如为马儿穿保护鞋一样。

马是奇蹄目的成员。其他成员包括斑马和驴，它们都有相同形态的脚蹄。

A horse hoof is a structure surrounding the distal phalanx of the 3rd digit (digit III of the basic pentadactyl limb of vertebrates, evolved into a single weight-bearing digit in equids) of each of the four limbs of Equus species, which is covered by complex soft tissue and keratinised (cornified) structures. Since a single digit must bear the full proportion of the animal's weight that is borne by that limb, the hoof is of vital importance to the horse. The phrase "no hoof, no horse" underlines how much the health and the strength of the hoof is crucial for horse soundness.
