Patrick Dennistoun McGorry FAA FASSA FAHMS FRCP FRANZCP (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.

Professor McGorry was awarded the Centenary Medal in 2003 in recognition of his work on the EPPIC program.

The early psychosis model of care has garnered bipartisan support, and was originally funded under the Gillard Labor government in 2011.

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."

On 25 September 2012, Western Australian member of parliament Martin Whitely made a speech in parliament criticising the Australian Government for its support of McGorry's proposals.

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.

In 2018 the Turnbull Government committed to a three-year extension of funding ($13.5 million) to Orygen, The National Centre of Excellence in Youth Mental Health, and also committed an additional $30 million to headspace.

The success of headspace has seen it grow from 10 centres in 2007 to 110 in 2018 that are accessed by 100,000 young people each year, with an additional 30,000 accessing its online service eheadspace.

In January 2010 McGorry was named Australian of the Year for his services to youth mental health.

In June 2010 he was appointed an Officer of the Order of Australia.

In 2013 Professor McGorry was honoured with the National Alliance on Mental Illness Scientific Research Award, the first time the award has been bestowed upon a researcher outside of the United States.

In 2015, McGorry was awarded the Lieber Prize for Outstanding Achievement in Schizophrenia Research, given by the Brain & Behavior Research Foundation.

In 2018 he was awarded the Lifetime Achievement Award by the Schizophrenia International Research Society.

He is a member of many advisory committees both nationally and internationally, including the Million Minds Mission for mental health launched by the Australian Government in 2018.
