Sri Lanka participated at the 2018 Asian Games in Jakarta and Palembang, Indonesia from 18 August to 2 September 2018.

The Sri Lankan team was scheduled to consist of 185 athletes (138 men and 47 women), marking the large contingent the country has sent to a single edition of the Asian Games. The Sri Lankan team will compete in 28 sports, marking its debut in the sports of baseball, canoeing, roller sports and triathlon. Approximately, 60 officials and coaches were also a part of the contingent, making the total team size 245. However, the athletics team was cut to 14 athletes (from 25), making the team size 174 (128 men and 46 women), which would still make this the biggest team the country has sent to the games. Further changes made the final team size at 173 athletes (131 men and 42 women). Sri Lanka will also have an athlete competing in the demonstration event of esports.

On August 17, 2018, weightlifter Dinusha Gomes was announced as the country's flag bearer at the opening ceremony.

The National Shooting Sports Federation of Sri Lanka declined to enter any athletes for the games because the National Olympic Committee of Sri Lanka refused a request for a coach to go with the team.

Sri Lanka failed to win a medal, being jointly ranked with eight other countries for last place. The country's highest placement was two fourth-place finishes for the men's 4 × 400 m track and field relay team and the men's rugby sevens team.

The team was later reduced to 12 athletes (seven men and five women), after the entries of Ushan Thiwanka and Upamali Ratnakumari were rejected by organizers due to the national organization forgetting to enter their names on time. The track and field team failed to win a medal for the third straight Asian Games. The top placing performance was fourth by the men's 4 × 400 m relay team who finished with a time that was off the Sri Lankan record by 0.03 seconds.
