About the event

Join us for London’s St Patrick’s Day on Sunday 16 March in Trafalgar Square. Enjoy the best of Irish arts, culture, food, and music, along with the spectacular parade.

The Mayor’s annual shindig has become a highlight of London’s cultural calendar, uniting Londoners and visitors in celebrating the many contributions the Irish community have made to our great city.

St Patrick’s Day is the perfect opportunity to honour the enduring friendship between the British and Irish people and begins with an annual parade of Irish marching bands, dance troupes and pageantry which travels from Hyde Park Corner to Trafalgar Square, where the action continues.

The main stage hosts another world-class line up of Irish acts, programmed by the London Irish Centre, plus there's a plethora of family activities and a great selection of food stalls and a bar to enjoy.

We look forward to welcoming you to St Patrick's Day.
