Leeuwin Estate is an Australian winery and restaurant based in the Margaret River wine region of Western Australia.

[3][4] Robert Mondavi provided significant advice during the planning and setup stages of the estate after contacting the Horgans in 1972 to promote the potential that Margaret River had as a wine region and to look for investment opportunities.

The winery is still owned by Denis and Tricia Horgan, with their son Justin and daughter Simone working as the company Joint Chief Executive Officers.

[20] Leeuwin Estate hosts an annual series of concerts featuring major Australian and international performers.

[3][5][22] In February 2005, a concert was performed by Sting that attracted 6,000 attendees and raised over $4 million for the 2004 Indian Ocean earthquake and tsunami relief efforts.
