The 2019 AFF U-22 Youth Championship or AFF U-22 LG Cup 2019 was the 2nd edition of the AFF U-22 Youth Championship organised by the ASEAN Football Federation (AFF). Indonesia won the tournament after defeating Thailand 2–1 in the final. The tournament was held from 17 to 26 February in Phnom Penh, Cambodia. This was its first as an under-22 tournament, with the previous edition being an under-23 tournament. 2005 AFF U-23 Youth Championship winners Thailand were the defending champions, as there was no competition from 2006 to 2018 and the 2011 edition was cancelled.
