Alexander Melei Rose is a Samoan-American athlete, competing primarily in the discus throw and occasionally in the shot put and the hammer throw. He represented Samoa at the 2016 Olympics, and 2020 Summer Olympics, as well as the Commonwealth Games and Pacific Games.

The discus throw, also known as disc throw, is a track and field sport in which the participant athlete throws an oblate spheroid weight — called a discus — in an attempt to mark a farther distance than other competitors. It is an ancient sport, as demonstrated by the fifth-century-BC Myron statue Discobolus. Although not part of the current pentathlon, it was one of the events of the ancient Greek pentathlon, which can be dated back to at least 708 BC, and it is part of the modern decathlon.
