The deal, believed to be worth a significant six-figure sum to the club, represents a major coup and will see the Yorkshire men’s and women’s teams wear the famous brand from this season onwards.
Yorkshire are the third county to work with the American giants after Middlesex and Worcestershire.
Yorkshire’s county championship shirt has a modern take on the club’s proud traditions.
Capped players’ sweaters will have the traditional dark blue, light blue and yellow trim, detailed on the side of the jumpers and neckline.
This season’s Royal London One Day shirts will sport a collar to protect players from the sun during long days in the field.
A distorted Yorkshire rose is prominent through the shirt design and the Yorkshire yellow has been used on the trim.
The Vikings’ T20 shirt is arguably the most eye-catching kit to date, reverting predominantly to the favoured light blue, but distorting the rose design to offer a striking new look.
T20 captain David Willey, who provided valuable insight and input into the design of this season’s kits said: “I am really excited that the club will be partnering with Nike from this season.
“The players are always proud to wear a Yorkshire shirt and it is important to look and feel the part when playing.
“In terms of design for the T20 kit, I wanted something representative of the brand of cricket that I would like the lads to play this summer.
“It is bold and leaves an impression, and has gone down very well with the squad.”
The T20 strip is a striking light blue, while the County Championship sweaters will feature the traditional dark blue, light blue and yellow trim for capped players.
The One-Day Cup shirts will now sport collars to protect players from the sun, with a distorted Yorkshire rose prominent through the shirt design.
England, Yorkshire and Northern Diamonds’ Winfield-Hill said: “I love this season’s kit and I can’t wait to wear Nike for Yorkshire and the Northern Diamonds.
“Having a bespoke fit for the women’s squads is really important as the game continues to grow.
“We cannot wait to get back out there from May for what will be another big summer for women’s cricket.”
You can now pre-order Nike trainingwear, the County Championship, One Day Cup and Blast shirts from Yorkshire’s online shop.
A wider range of Nike merchandise will be launched in the coming weeks, including Yorkshire hoodies and t-shirts.
