The 2015 Football v Homophobia campaign kicks off at the National Football Museum in Manchester on Sunday.
A host of clubs from across the football pyramid - from Premier League pacesetters Chelsea and Manchester City to Dulwich Hamlet and Tonbridge Angels - have pledged their support.
The annual drive is aimed at raising awareness of homophobia, and some of the work being done to tackle it, in both professional and grassroots football.
Sunday's event marks the start of a month-long series of events and activities including 'dedicated' fixtures and panel debates.
The campaign coincides with LGBT History Month, which profiles groups, individuals and moments in time which have helped foster greater tolerance of the LGBT community in society more widely.
Lou Englefield, campaign director, is looking forward to this fifth year of activity.
'It's great to see that LGBT people are more visible than ever in football," she said.
"The last 12 months has seen an explosion of LGBT fans groups in the UK. Its clear the message that football is for everyone is really gaining momentum.
"Football v Homophobia is an independent campaign that everyone can support, from grassroots to the professional game.
"The FvH family, which includes people from all parts of the football community, continues to amaze us. We're looking forward to another great month of action in 2015."
Highlights include Stonewall FC's 'anti-homophobia friendly' against Dulwich Hamlet on Wednesday 11 February and panel discussion on homophobia by Women in Football (WiF) on Thursday 19 February at Broadcasting House, London.
Peter Clayton, CEO of Middlesex FA and member of The FA's Inclusion Advisory Board (IAB), is lending his support at the launch.
"The FA is encouraging everyone to report homophobic, biphobic and transphobic abuse when they see or hear it," said Clayton.
"A series of short films released by The FA last year reiterates the importance of this, and Kick It Out’s reporting app makes it easy for anyone to report anonymously and confidentially."
