In 2015, Harington joined a cast including Benedict Cumberbatch, Nicole Kidman, James McAvoy and Christopher Eccleston in a charity production of The Children’s Monologues, conceived by Oscar-winning director Danny Boyle. The performance took place at the Royal Court Theatre in London, on 25 October. Proceeds went to Boyle’s creative arts charity Dramatic Need, which helps vulnerable children in South Africa and Rwanda to build hope and self-belief in the face of conflict, trauma and hardship.
Since April 2016, Harington has been an ambassador for The Royal Mencap Society; a leading organisation in the United Kingdom focussed in helping people with learning disabilities that also provides support for their families and caregivers.
On 16 April 2016, he was appointed as a patron of Longlands Care Farm, a charity located on a working livestock farm in Worcestershire, in which they care for, mentor and support disadvantaged and vulnerable young people aged 14 – 19 who are not succeeding in mainstream education.
On 12 September 2016, Harington, as well as Cate Blanchett, Chiwetel Ejiofor, Peter Capaldi, Douglas Booth, Neil Gaiman, Keira Knightley, Juliet Stevenson, Jesse Eisenberg, and Stanley Tucci, featured in a video from the United Nations’ refugee agency UNHCR to help raise awareness of the global refugee crisis. The video, titled “What They Took With Them”, has the actors reading a poem, written by Jenifer Toksvig and inspired by primary accounts of refugees, and is part of UNHCR’s #WithRefugees campaign, which also includes a petition to governments to expand asylum to provide further shelter, integrating job opportunities, and education.
In August 2017, with a video backing Mencap #StopSleepInCrisis, Harington called on the government to fund six years’ back pay for overnight carers. In a personal message of support, Harington said: “The learning disability sector in the UK is on the brink of crisis. It is faced with a back-pay bill of £400 million which it cannot pay. Many of the providers of this essential, ‘sleep-in’ service, face bankruptcy. And some of the most vulnerable people in our society will be left, without care, without hope and without an independent future. Stand with Mencap and stand with the incredible people our colleagues support and care for every day.”
In 2018, he joined Tom Hiddleston, Kristin Scott Thomas, Jeremy Irons and Indira Varma among others for a one-off charity gala celebrating the life and work of Harold Pinter, directed by Jamie Lloyd. The event Happy Birthday, Harold took place at the Harold Pinter Theatre in London, on 10 October and comprised a varied programme of Pinter’s work. Proceeds went to Amnesty International and Chance to Shine – two of Pinter’s favored charities.
