A diving platform or diving tower is a type of structure used for competitive diving. It consists of a vertical rigid "tower" with one or more horizontal platforms extending out over a deep pool of water. In platform diving, the diver jumps from a high stationary surface. The height of the platforms - 10 metres (33 ft), 7.5 metres (25 ft) and 5 metres (16 ft) - gives the diver enough time to perform the acrobatic movements of a particular dive. There are additional platforms set at 3 metres (9.8 ft) and 1 metre (3.3 ft). Diving platforms for FINA sanctioned meets must be at least 6 metres (20 ft) feet long and 2 metres (6.6 ft) wide. Most platforms are covered by some sort of matting or non-slip surface to prevent athletes from slipping.

All three levels of the platform are used in JO and NCAA competition. Each level offers a distinct degree of difficulty (DD) and therefore could yield different scores for divers.
