The thirteenth and final season of the Australian police drama Blue Heelers premiered on the Seven Network on 1 April 2006 and aired on Saturday nights at 8:30 pm. The 11-episode season concluded 4 June 2006, due to its cancellation by the Seven Network as a result of its sharp decline in ratings. When, in late 2005, the time came to renew Blue Heelers, Seven commissioned eleven further episodes to be produced, but its future after this was still undecided.
