The 2006–07 season was the second season of competitive football played by Central Coast Mariners. The club ended the 2006–07 A-League in sixth, and so did not qualify for the finals. They failed to retain their A-League Pre-Season Challenge Cup title, losing to Adelaide United in the final. In the transfer window, Central Coast signed Australian international Tony Vidmar and defender Vuko Tomasevic. The short term contracts of Brad Porter and Jamie McMaster were also extended.
