Shannon (1941–1955), named Shannon II in America, was an outstanding Australian Thoroughbred racehorse who was inducted into the Hall of Fame. He created new racecourse records in Australia before he was sold to an American buyer who exported him to California in 1948. There Shannon equalled the world record of 1:473⁄5 for the nine furlongs in winning the Forty Niner Handicap Stakes, then one week later equalled the world record of 1:594⁄5 for a mile and a quarter. Shannon was named the 1948 American Champion Older Male Horse. At stud in America he proved to be a good sire.

The Australian Racing Hall of Fame is part of the Australian Racing Museum which documents and honours the horseracing legends of Australia. The museum officially opened in 1981 and created the Hall of Fame in 2000.
