Peabody chief executive Brendan Sarsfield is to leave his role next summer.
Sarsfield had been chief executive of Family Mosaic for more than 16 years before he took charge of Peabody in July 2017, following the merger of the two.
Peabody will now start its search for a new chief executive.
Sarsfield said: “It has been a great privilege to lead Peabody, but after 20 years as a chief executive, I feel it is the right time to start looking at new challenges and opportunities.
“I want to say thank you to all of my Peabody colleagues and those I have worked with since 2001. Thank you for your support, your hard work, and for your dedication to helping people make the most of their lives. It’s been an honour to play my part in the legacy of Peabody and I look forward to welcoming my successor on board.”
Peabody chairman Lord Kerslake added: “It has been a great pleasure working with Brendan over the last few years. Under his leadership, we have prioritised social rented homes at low rents for people in need.
“His commitment to our social purpose and Peabody has been highly effective, and I wish him all the very best for the future.”
