British number one Jack Draper and world number six Jessica Pegula will play at Queen's next year.
Draper, ranked 10th in the world, reached the semi-finals this summer where he lost in three sets to eventual runner-up Jiri Lehecka.
American Pegula will make her tournament debut in 2026, a year after women's tennis returned to Queen's for the first time since 1973.
Last week it was confirmed defending men's champion Carlos Alcaraz and 2025 women's runner-up Amanda Anisimova will return.
"I'm really looking forward to being back – I played some really good tennis this year and it's one of my favourite tournaments, being in front of a home crowd, I just love the atmosphere," said Draper, 23.
