Dolgopolov and Ward will join Andy Murray, Jo Wilfried Tsonga, Tomas Berdych and Juan Martin del Potro in a line-up that also features Lleyton Hewitt, Grigor Dimitrov and defending champion Marin Cilic.
Ward reached the semi-finals in 2011, beating the 2010 champion Sam Querrey, and Stanislas Wawrinka en-route, and the 26-year-old helped the Britain to a famous Davis Cup victory over Russia earlier this year.
Tournament Director Chris Kermode said: “James Ward made a huge impression on the crowd in reaching the semi-finals in 2011, and his performance in Davis Cup recently was heroic. The head of men’s tennis in Britain, Leon Smith, had no hesitation in recommending James for a wildcard and we look forward to welcoming him back in June.”
The Aegon Championships will award three more wildcards before the event begins.
The tournament will be broadcast live, from June 10-16, on Eurosport.
