Neftochimic (Bulgarian: Нефтохимик) was a Bulgarian association football club based in Burgas. The club participates in the A Group, the first tier of Bulgarian football. Neftochimic was founded in 2009 and was claimed that is the official successor of the traditions and successes of the disbanded Naftex Burgas, which was founded in 1962.
The club was created in 1962 by a group of workers, laying the foundations of the future Petroleum Refinery Neftochim, which had not yet been named. The team startеd in A regional group under the name of Stroitel. In 1964 the Refinery was finally named Neftochim and the team's name was also changed to Neftochimic. Year later, the team earned its promotion to B PFG.
In 1993, Dimitar Dimitrov signed as a manager of the team and it won the Bulgarian Eastern B PFG and qualifies in the Bulgarian top division for the first time in its history. Neftochimic finished at 8th place in its first season and reached the semifinals of the Bulgarian Cup eliminating champions Levski Sofia on its way. The second season in the Bulgarian A PFG was among the most successful season in the history of the club. Neftochimic finished 4th and won the Professional League Cup. In 1997, Neftochimic finished second after a series of referee's mistakes in favor of champions CSKA Sofia and won again the Professional League Cup. In the following years, Neftochimic established itself as the one of the best teams in the country regularly finishing in places allowing the team to participate in the UEFA Cup.
In February 2004, Portochanov resigned as a president of Naftex and the club began experiencing serious troubles. Many of the very strong and experienced players that brought success to Naftex were sold and the new management managed the club carelessly allowing it to fall out of the A PFG in 2006.
On 6 July 2009, Naftex Burgas stopped its existence. On 7 July the amateur football club Athletic was renamed to Neftochimic 1986 and was subsequently declared by the owners as a successor of the old team. It began playing in the 2009-10 Bulgarian V AFG, the third tier of football in the country, finishing 3rd in its debut season and barely missing on a promotion. During the following 2010-11 season the team finished second, completing a quick return to professional football. Neftochimic also won the 2011 Bulgarian Amateur Football League Cup.
At the conclusion of the 2011–12 B PFG the Sheiks barely missed on a place in the promotion play-off, finishing in 3rd place just two points behind PFC Botev Plovdiv. However, at the halfway stage of the 2012–13 B PFG they were on top of the division and get promotion for A PFG. On 27 June 2014 it was announced that the club was dissolved due to financial debts.
