The England and Wales Cricket Board (ECB), the professional game and Sky Sports will come together to celebrate the third year of Rainbow Laces this weekend.
Rainbow Laces is a Stonewall campaign which aims to ensure the message is heard that sport is a game for everyone.
All 18 men's First-Class Counties and the six Kia Super League teams will play across the period, which runs from Friday August 9 to Monday August 12.
Notts Outlaws will be competing twice over the weekend, with a trip to Edgbaston to face Birmingham Bears followed by an away fixture at Durham.
Rainbow laces have been sent to every team, while stumps and flags have also been distributed.
Speaking as part of the LGBTQ+ community, I've always found cricket to be a really all-embracing and welcoming sport," said England and Yorkshire Diamonds cricketer Lauren Winfield.
"It really should be a sport for everyone, regardless of race, background, gender or sexuality.
"It's great to see the ECB and cricket in a wider sense continue to support Rainbow Laces - and to have marched at Pride for the last two years. It shows great inclusivity and value to younger fans that cricket is a game for all."
Steve Gillies, a club cricketer at St Chad's Broomfield CC who is gay, said "Personally, seeing rainbow stumps at games and seeing players wearing rainbow laces just gives me a greater sense of belonging.
"There was a time when I worried cricket wouldn't accept me, that I would forever be an outcast - now I wear rainbow laces every time I walk out to the middle.
"It's a small touch that allows me to fully express who I am, with no fear of a negative reaction. You can't put a price on that."
