The 2018–19 season was the 14th season for Central Coast Mariners FC since its establishment in 2004. The club participated in the A-League for the 14th time and the FFA Cup for the fifth time.
The Mariners were defeated in the first round of the 2018 FFA Cup by Adelaide United.
This season saw the appointment of Mike Mulvey as head coach following the departure of Paul Okon late in the previous season. Mike Mulvey lasted only until round 21 before becoming the forth coach sacked in 5 seasons. In the transfer window, the club re-signed two former players: all-time top scorer Matt Simon and New Zealand midfielder Michael McGlinchey. In pre-season, Jamaican Olympic sprint champion Usain Bolt also came to the club to train on an indefinite basis. Mulvey was sacked by the Mariners following their 8–2 loss at home against Wellington Phoenix.[1] Alen Stajcic was named as caretaker to carry out the remainder of the season.[2]

The Mariners ended the previous A-League season in last place after losing to F3 Derby rivals Newcastle Jets 8–2 on the final matchday.[3] Paul Okon had stepped down as head coach late in the season and his replacement, Wayne O'Sullivan, had his contract terminated soon after season's end.[4] Former Gold Coast United and Brisbane Roar coach Mike Mulvey was named as the new coach in April 2018.[5]
