The National Asians High School Debate Championship, more popularly known as NAsHDC, is a debate tournament in the Philippines sponsored by the De La Salle University-Manila. It is one of two national debate tournaments in the Philippines, the other being the Philippine Schools Debate Championship sponsored by the Ateneo de Manila University.
Every year after its inception in 2003, NAsHDC has consistently expanded in participation and support. Former partners include the Children's Museum and Library Incorporated (CMLI) and the Friedrich Naumann Stiftung (FNS). The tournament is also consistently supported by the National Youth Commission (NYC) and endorsed by the Department of Education. In 2008, the tournament was renamed the Manila Bulletin National Asians High School Debate Championship in light of the Manila Bulletin being the NAsHDC co-presenter.
In 2018, De La Salle University-Manila, in partnership with Unilab and Business Mirror, hosted NAsHDC again after a 7-year hiatus.
In NASHDC 2026, the La Salle Debate Society added the Veridian Cup Category. Debaters from Visayas and Mindanao are eligible to compete in the said category. However, the category did push through to have a finals series and instead only awarded the Top 3 Veridian-eligible speakers in the preliminary rounds. The continuation of the category in future iterations is still unknown.
Tournament Format NAsHDC uses the Asian Parliamentary debate format. It is a 3-on-3 parliamentary debate style that was founded in 1994 in University of Tasmania, Hobart, Australia. There is a separate novice division in NAsHDC.
