Wear A Hat Day 2026

Wear A Hat, Raise Money, Change Lives

Our annual fundraiser is back! Join in on Friday 27th March, wear a hat and hold an event to help fund the fight to find a cure for all types of brain tumours.

Since Wear A Hat Day launched in 2010, supporters taking part have raised more than £2.2 million, enabling scientific breakthroughs at our Centres of Excellence and helping us push governments to invest more in life-saving research.

Whether you favour a fedora, sport a sombrero or pop on a Panama – whatever your style – by wearing a hat and holding a fundraising event, you’ll help bring hope to the one in three people who knows someone affected by a brain tumour.

You can make an even bigger impact by inviting others to join in the fun.

You could hold a Wear A Hat Day event:

  • In your community 

    Whether it’s in your home, at a community group, or with your local sports team, round up your family, friends and neighbours for a fantastic fundraiser.

What is Wear A Hat Day? 

Wear A Hat Day is one of the UK’s biggest and best-loved brain tumour awareness and fundraising days, bringing people together across the nation as they put on their favourite hats and make a donation, or attend a fundraising hat-themed event.

Since the inception of Wear A Hat Day, Brain Tumour Research has become synonymous with hats and hatting. A bespoke pink silk top hat created for us by Lock & Co. – the world’s oldest hat shop – has been our emblem and is an instantly recognisable part of Wear A Hat Day every year. Wearing a hat reminds us of those who have been personally affected by this devastating disease and helps spread awareness of our cause.
