Immediately after Hird retired from playing football, there was much speculation as to whether he would be interested in a coaching role at a club in the AFL, but primarily at Essendon. After initially dodging questions about his future, Hird stated in August 2010 that "There's something in me, deep in my heart, that says at some point I want to coach Essendon". These words came as a surprise to many, including former
premiership teammate Matthew Lloyd, who said that Hird had "changed his whole persona in regards to how he's answering his questions... Just in regards to saying, 'I'll coach one day. I want to coach Essendon one day'. Even those type of words, I haven't heard before." These comments by Hird, considered to be Essendon's "favourite son", furthered speculation towards the future of then-Essendon coach
Matthew Knights. A rumour emerged following these comments suggesting that Hird was part of an unofficial agreement with the Essendon board to replace Matthew Knights for the
2011 AFL Season. However, two days after Hird's initial comments, he announced that he had changed his mind due to the intense division and speculation over Matthew Knights' future following Hird's initial comments. Hird stated that he was ruling himself out of coaching Essendon for at least three years. Hird's coaching career began with the Bombers winning against triple preliminary finalists the in the first round. Wins against , the (by a record margin of 139 points), and in the first eight rounds saw the Bombers in the top four by round eight, but a draw against , losses to and and a five-game losing streak halfway through the season saw Essendon drop to tenth on the ladder after Round 14. Hird's team then won by four points against the previously undefeated in Round 15, whom assistant coach
Mark Thompson was coaching against for the first time since his exit from the club. Prior to that match, Essendon had one of the worst records among current AFL clubs against Geelong in recent times, having only beaten the club once since 2003. Hird coached Essendon to the 2011 finals, where they lost against rivals in an elimination final at the MCG. At the start of the 2012 season, Essendon won eight of their first nine games (the only loss being by one point to Collingwood on ANZAC Day), at which point Essendon were in first position on the league ladder. The club then won 11 of their first 14 games but this was followed by seven consecutive losses until the end of the season. The club ended 2012 in 11th place. A spate of soft-tissue injuries accompanied the decline, as did noticeable fatigue in other players, leading to criticism of the club's fitness and conditioning coach
Dean Robinson and, indirectly, Hird and his assistant Thompson for having overseen Robinson's program. The 2013 season was initially a good one for Hird and the football club, during which the team was second on the AFL ladder with a 13–3 win–loss record after 17 rounds. However, internal pressure on the club finally took its toll on the players and coach when the AFL banned Essendon from participating in the 2013 finals series. The club on-field performances fell away and lost five of their last six games. In August 2013, he was suspended from coaching for 12 months when he was charged by the AFL with conduct prejudicing the game in relation to his role in the
Essendon Football Club supplements controversy. He returned to the club following the 2014 season. Shortly after returning from his suspension, on 2 October 2014, it was reported that Hird was to be sacked by Essendon due to his determination to lodge an appeal against the Federal Court decision handed down the previous month when the club had chosen not to. On 18 August 2015, following a 112-point loss to in Round 20, 2015—and a dismal season overall for the Essendon Football Club, by which time they had a 5–14 win–loss record and were fifteenth on the AFL ladder—Hird resigned as senior coach.
