Milorad Čavić (Serbian Cyrillic: Милорад Чавић; born on May 31, 1984) is an American-born Serbian swimmer.

Born in Anaheim, California and a citizen of both Serbia and the United States, he attended Tustin High School in California, where he set four CIF records and a national high school mark in the 50 yd freestyle. While swimming for the University of California, Berkeley and training with Mike Bottom, Čavić set a new school and Pac-10 record in the 100 yd butterfly (45.44 s).

Representing Serbia at the European Short Course Swimming Championships in Dublin 2003, Čavić won the gold medal in 100 m butterfly and set a new world record. He also won a silver medal in 50 m freestyle. Čavić defended his European 100 m title on subsequent short-course championships in Helsinki 2006 (finishing 50.63), Debrecen 2007 (finishing at 50.53) and Rijeka 2008 (finishing at 49.19 and setting a new European record). He also took silver on 50 m butterfly in Rijeka.

On December 14, 2007 Čavić defended his European championship in the 100 m butterfly in Helsinki, finishing at 50.63 seconds. On December 14, 2007, the sprinter defended his European championship again in the 100 m butterfly in Debrecen, finishing at 50.53 seconds.

Michael Fred Phelps (born June 30, 1985) is an American swimmer who has, overall, won 16 Olympic medals—six gold and two bronze at Athens in 2004, and eight gold at Beijing in 2008, becoming the most successful athlete at both of these Olympic Games editions. In doing so he has twice equaled the record eight medals of any type at a single Olympics achieved by Soviet gymnast Alexander Dityatin at the 1980 Moscow Summer Games. His five gold medals in individual events tied the single Games record set by compatriot Eric Heiden in the 1980 Winter Olympics and equaled by Vitaly Scherbo at the 1992 Summer Games. Phelps holds the record for the most gold medals won in a single Olympics; his eight at the 2008 Beijing Games surpassed American swimmer Mark Spitz's seven-gold performance at Munich in 1972. Phelps' Olympic medal total is second only to the 18 Soviet gymnast Larisa Latynina won over three Olympics, including nine gold. Phelps also holds the all-time record for most gold Olympic medals, at 14.
