Patrick Dennistoun McGorry[1] (born 10 September 1952) is an Irish-born Australian psychiatrist known for his development of the early intervention services for emerging mental disorders in young people.

McGorry also advocated strongly for the establishment of the Australian government funded National Youth Mental Health Foundation, which became headspace, and is a founding board member of that organisation.

[5] McGorry and his colleagues developed an approach for young people who have symptoms of psychosis for the first time, based at the EPPIC clinic in Melbourne.

[6] This EPPIC clinic has played a key part in an early psychosis treatment paradigm for psychiatry[7][8][9] and has led to significant reform of mental health services,[10] especially in the United Kingdom.

In 2011, a systematic review concluded: "There is some support for specialised early intervention services, but further trials would be desirable, and there is a question of whether gains are maintained.

[38] Early intervention in psychosis has paved the way for a broader model of care ("headspace") that targets a range of youth mental disorders.

During the 2013 Australian Federal election, McGorry appeared in the media together with then Opposition Leader Tony Abbott at the launch of the Liberal-National Coalition's mental health policy.

[50] On 10 October 2023, McGorry initiated and was one of 25 Australians of the Year who signed an open letter supporting the Yes vote in the Indigenous Voice referendum.
