2013 Australian Open – Boys' Singles

Luke Saville was last year's champion; however, being no longer a junior player, he did not defend his title.
Compatriots to Saville and home players, Nick Kyrgios and wildcard Thanasi Kokkinakis played off in the final. Kyrgios, who was also a winner of Roland Garros and Wimbledon in junior doubles, defeated Hopman Cup player Kokkinakis, 7–6^(7–4), 6–3.
