The Girls Singles tournament of the 2012 BWF World Junior Championships was held from October 30 until November 3. The defending champion, Ratchanok Intanon, who won the tournament for 3 years in a row decided not to take part this time even though her age was still eligible.

Japanese girl Nozomi Okuhara, who was beaten by Intanon in the semi-final of the previous year's tournament, won the all-Japanese final against her teammate Akane Yamaguchi 21-12, 21-9.
