Jetstar Asia Airways Pte Ltd (operating as Jetstar Asia) is a low-cost airline based in Singapore. It is one of the Asian offshoots of parent Jetstar Airways, the low-cost subsidiary airline of Australia's Qantas airline. It operates services to regional destinations in Southeast Asia to countries such as Myanmar, Cambodia, Malaysia, Philippines, Thailand and Vietnam. It also flies to regional routes in East Asia such as Japan, Taiwan and Hong Kong. It is the main feeder airline for its parent company Jetstar Airways for budget passengers flying to Australia. Its sister airlines include Jetstar in New Zealand, Jetstar Pacific and Jetstar Japan.

Jetstar Asia was launched in 2004 as a partnership between Qantas, holding a 49% stake in the airline, Singaporean businessmen Tony Chew (22%) and FF Wong (10%) and the Singapore government's investment company, Temasek Holdings (Private) Limited (19%). It received its Air Operator's Certificate from the Singapore government on 19 November 2004.

Due to its belated entry into the market, the airline differentiated itself from its competitors by flying further; anywhere within a 5-hour radius from Singapore while its competitors flew to destinations within a 4-hour radius from Singapore. The airline announced 7 routes to Shanghai, Hong Kong, Taipei, Pattaya, Jakarta, Surabaya and Manila; the most ambitious start-up plan compared to any of its Asian rivals, which would have given it the widest international coverage.
