Since its founding, Boston has served as a beacon of hope and strength for the rest of the world. On One Boston Day, we show the world that Boston's flame burns as bright as ever.

Mayor Marty Walsh announced One Boston Day

April 15th is One Boston Day. This annual tradition was started to commemorate the tragic events surrounding the Boston Marathon on April 15, 2013.

Over the past year, we have all been tested in ways we could not have imagined. The spirit of One Boston Day is more important than ever, as we continue to battle a public health crisis.

Our hearts are heavy with collective grief for the lives lost during the pandemic. And, we are inspired by the resiliency, generosity, and strength of our essential workers.

This year, for One Boston Day, we’re asking you to stand together, by staying apart. Make this your day of reflection and service.
