The Asian Le Mans Series (AsLMS) is an Asian sports car racing endurance series created by the Automobile Club de l'Ouest (ACO) and based in Asia. It is the successor to the defunct Japan Le Mans Challenge which folded in 2007 after its second season. The ACO aims to attract teams and drivers from Asian countries.

A teasing race was to be held in Shanghai, China on November 1–2, 2008 but was later cancelled. The inaugural season's race, the 2009 1000 km of Okayama, was held on 30 October and 1 November 2009 at Okayama, Japan with one 500 km race per day. It was the only event of the inaugural season. A second Asian Le Mans Series event, scheduled for the Shanghai International Circuit, China, on 7 and 8 November was cancelled by the ACO due to economic circumstances. The winning teams in each of the four categories (LMP1, LMP2, GT1 and GT2) earned automatic invitations to the 2010 24 Hours of Le Mans. The series was relaunched for the 2013 season with an announcement at the 2012 24 Hours of Le Mans.

Following the end of the All Japan Sports Prototype Championship (JSPC) in 1992 there was no major endurance series involving sports prototypes in Asia, although there was a grand tourer championship in the All Japan Grand Touring Car Championship (JGTC), the predecessor to today's Super GT series.

Plans for a new endurance championship were initially conceived by Don Panoz and backed by the ACO in 2000 with plans for an Asian-Pacific Le Mans Series, modeled after his American Le Mans Series and planned European Le Mans Series for 2001. Two previews of this event were held. The 1999 Le Mans Fuji 1000km at the Fuji Speedway in Japan combined Le Mans cars with JGTC machines for automatic entries to the 2000 24 Hours of Le Mans. This idea was followed by the American Le Mans Series with the 2000 Race of a Thousand Years race at the Adelaide Street Circuit in Australia. These two events served as a precursor to the planned APLMS series, and at the time of the creation of ELMS, Don Panoz announced his intention to hold an exhibition APLMS race at Sepang International Circuit in Malaysia in late 2001.

However, the European Le Mans Series suffered from a lack of entrants during its debut season and was eventually canceled. Don Panoz decided that the APLMS would likely have even less interest. Thus the APLMS exhibition race and all plans for an Asian series were scrapped.

The ACO attempted to develop their own championship modeled on their own Le Mans Endurance Series in 2006 with the development of the Japan Le Mans Challenge, overseen by the Sports Car Endurance Race Operation (SERO). It too lacked competitors and was canceled after its second season.

In 2009, a reborn Asian Le Mans Series held an inaugural event in Okayama, Japan with two 500 km races. A 1000 km race in Zhuhai, China, was held as part of the Intercontinental Le Mans Cup in 2010, and it was also part of the Asian Le Mans Series.

At the 2012 24 Hours of Le Mans the ACO announced the revival of the Asian Le Mans Series for the 2013 series. The format will be run very similarly to the European Le Mans Series, with the ACO expecting around 16-18 cars for the first relaunched season. However, only 8 cars showed up for the first race of the season, making it the smallest ever grid in ACO sanctioned racing. This record was broken a year later when only six cars started the first race of the 2014 season at Inje.
