The Asian Formula Three Championship was a single-seater racing series based in South East Asia. It is one of a number of national and international Formula Three championships that form part of an established "career ladder" below Formula One. It was sanctioned by the Automobile Association of the Philippines, and was most recently promoted as the Asian F3 Pacific Series. The 2009 series collapsed through a lack of competitors with some teams dispersing to other Formula 3 series in the region.
