Former world No.1s Osaka and Wozniacki will both play in the main draw at Wimbledon for the first time in five years after becoming mothers.
Wozniacki was disappointed to miss out on a wild card at the French Open, and she told the PA news agency: "I have so many special memories.
"I won junior Wimbledon back in 2005, so it's a long time ago. There's something so special about playing on Wimbledon's Centre Court that you can't replicate anywhere else."
Former Wimbledon champion Kerber, another ex-world No.1 who has taken time away from the sport to start a family, has also received a wild card along with British players Francesca Jones, Heather Watson and Yuriko Miyazaki.
Raducanu will return to the All England Club, where she made her breakthrough by reaching the fourth round in 2021, for the first time in two years following wrist and ankle surgery last year.
The former US Open champion reached the semi-finals of the Rothesay Open in Nottingham last week in an encouraging start to her grass-court campaign.
In the men's draw, the initial batch of wild cards have gone to seven British players, including last year's junior champion Henry Searle.
Dominic Thiem, though, is set to have to go through qualifying if he is to make a final appearance at the All England Club, with the Austrian announcing last month that he will retire at the end of the season because of wrist problems.
