Chinamax (also known as Valemax) is a standard of ship measurements that allow conforming ships to use various harbours when fully laden, the maximum size of such a ship being 24 m (79 ft) draft, 65 m (213 ft) beam and 360 m (1,180 ft) length overall.

The standard was originally developed to carry very large loads of copper ore to China from Brazilian port facilities operated by mineral firm Vale.

Correspondingly, harbours and other infrastructure that are "Chinamax-compatible" are those at which such ships can readily dock. Unlike Suezmax and Panamax, Chinamax is not determined by locks or channels, or bridges—the Chinamax standard is aimed at port provisions and the name is derived from the massive dry-bulk (ore) shipments that China receives from around the globe.
