The 2013–14 B Group was the 59th season of the Bulgarian B Football Group, the second tier of the Bulgarian football league system. The season starts on 3 August 2013 and finished in May 2014. On 21 June the Executive Committee of Bulgarian Football Union confirmed that the number of teams for the new season will remain 14. The teams play twice against each other, once home and once away, as it was the previous season. At the end of this season again there are just 2 teams promoted to the top tier of Bulgarian football (A PFG), but since there are 4 teams relegated from the top league so as to reduce the number of teams in it, there will be 4 teams relegated from B PFG at the end of the season as well, in order to keep the number of teams in the division 14.
