The league was operated by the Ekstraklasa SA.
The season started on 14 July 2017 and concluded on 20 May 2018. It is the first Ekstraklasa season to use VAR. After the 21st matchday the league went on a winter break between 18 December 2017 and 9 February 2018. The regular season was played as a round-robin tournament.

Each team played a total of 30 matches, half at home and half away. After the 30th round, the league split into two groups: championship round and relegation round. Each team played 7 more games. So, finally each team played a total of 37 matches. The team at the top of the Championship round wins the league title. The two teams at the bottom of the Relegation round are demoted to I liga for the 2018–19 season. This was the fifth season to take place since the new playoff structure has been introduced.
The defending champions were Legia Warsaw, who won their 12th Polish title the previous season.
Legia successfully defended their title, sealing the league trophy for a 13th time in dramatic circumstances as their deciding game against Lech Poznan was abandoned due to flares and pitch invasions by Lech fans. Legia were awarded the tie 3-0 and three points secured 1st place.
