Some of Hollywood's biggest names, plus a skateboarding legend, are pitching in to help Tyre Nichols' mother and stepdad ... with big donations to his memorial fund.
TMZ combed through more than 33,000 donations to Tyre's official GoFundMe and found a ton of celebs who donated money.
"Love Song" singer Sara Bareilles, pro skateboarder Tony Hawk and comedian Lil Rel Howery each pledged $1,000 ... as did "Shea Butter Baby" singer Ari Lennox.
The fundraiser is being organized by Tyre's mom, RowVaughn Wells, who says her and her husband's lives have been turned upside down by Tyre's death, which came after he was brutally beaten by Memphis police.
