Commenting on her appointment, Dugdale said: “Stonewall is fit for the future.”
She said the charity was ready to navigate “these turbulent times”, influence policy and create more safe and inclusive places for people to feel safe and thrive.
“We won’t stop until everyone, everywhere has equal rights,” she said.
Stonewall said the ex-politician would bring a wealth of experience in law-making and public policy.
Its chief executive Simon Blake said: “She has a deep commitment to public service and a long history of advocating for LGBTQ+ equality.
“Her skills and experience across academia, politics and welfare will be an asset to Stonewall as we deliver on our purpose to create a safe and equal world for LGBTQ+ people to live, work and thrive.”
Outgoing chairwoman Ayla Holdom said it was a joy to be handing over to Dugdale who she said was “the perfect leader”.
She added: “Serving in this role has been a profound privilege, made all the more meaningful by the remarkable trustees I’ve served alongside.
“I step down proud of the strong foundations Stonewall has built, guided by clarity of purpose and strategy to navigate the turbulence of our times.”
