The 2013 A Lyga, also known as SMSCredit.lt A Lyga for sponsoring purposes,[citation needed] is the 24th season of the A Lyga, the top-tier association football league of Lithuania. The season started on 9 March 2013 and ended on 10 November 2013. FK Ekranas were the defending champions.
The league changed its number of teams for the fourth time in a row, reducing it from ten teams in 2012 A Lyga to nine sides. As a consequence, the schedule reduced from 36 to 32 matches per team, with each team playing every other team four times in total, twice at home and twice away.
