The 2019 Heartland Championship, known as the 2019 Mitre 10 Heartland Championship for sponsorship reasons, was the 14th edition of the Heartland Championship, a rugby union competition involving the twelve amateur rugby unions in New Zealand. The tournament began with a round-robin stage in which the twelve teams played eight games each, from which the top four advanced to the Meads Cup semifinals, while fifth to eighth advanced to the Lochore Cup semifinals. In both of these knockout stages the top seeds (first and fifth) played at home against the lowest seeds (fourth and eighth), the second highest seeds (second and sixth) played at home against the third highest seeds (third and seventh) and the final featured the higher seed playing at home against the lower seed.
