June Goodchild died on Tuesday (July 6) at the age of 79 following a short illness.
Best known as the founder and former chairman of the Easterside Partnership, June was made an MBE in the 2007 New Year's Honours for her voluntary work on the estate.
She threw herself into community work in the mid-1990s in response to anti-social behaviour and a lack of facilities for youngsters.
Her many achievements included a successful campaign for CCTV cameras, reductions in anti-social behaviour and school absenteeism and the development of the successful Eco Easterside project.
A vocal supporter of Middlesbrough's first elected Mayor Ray Mallon in the run-up to the 2002 election, June went on to represent Ladgate Ward from May, 2015.
In August last year, she left the Council's Labour group to join the Middlesbrough Independent Group (MIG).
MIG group leader Councillor Antony High said: "June Goodchild embodies the community spirit not just of Easterside, but of Middlesbrough as a whole.
"Many of the improvements the area has seen in recent years are in no small part down to her tireless hard work, passion and commitment.
"It's been a privilege to know her as a colleague and as friend, and I know she will be greatly missed."
Middlesbrough Mayor Andy Preston said: "June's warmth and constructive directness touched so many lives in Easterside and beyond.
"She had a lovely family who will miss her - and we all will.
"Thank you June for being part of our lives, it was a privilege to know you."
