The club will remember former manager Brian Sparrow, Reds' fan Sarah Page and Suel Delgado, a former player in the club's Community Foundation, before Saturday's home game against Port Vale at The People's Pension Stadium.
Brian was Reds' manager when we reached the third round of the FA Cup in 1991-92 and also played for the club.
Sarah (pictured above right) was a lifelong Crawley Town fan who attended home and away games.
Her brother Kevin said: “Sarah's love affair for Crawley Town goes back to The Town Mead days when she accompanied our Grandad Alf to watch them in the old Southern League - the days of John Maggs in goal, Dave Haining at full back.
"She then helped Sue and Alan in the tea bar, but her true home was in the cow shed behind the goal. I'm not sure if it was the football that kept her going back or David Myers' tight shorts or Alan Lester's swept haircut in the late 1980s!
"She then took her loyalties to The People's Pension Stadium and watched Crawley make it into the Football League finally.
"She made many friends along the way and over the last few years was never far away from behind the goal with her nephew Josh and partner Steve and her son Bradley, when he could make it.
"Just as importantly, she was with her football family and I'm sure she will be missed by many and will leave a massive hole on the terrace. Town Team Together. COYR."
Suel was 20 when he died in Brighton following a car accident earlier this month. He was a member of the Foundation's football squads and a former pupil at Thomas Bennett Community College. He also played locally for several non-league clubs including Loxwood FC.
