The big-serving Serbian, who last week beat Britain's Andy Murray in Melbourne to win his second Grand Slam title, has joined world number one Rafael Nadal in announcing his entry for the tournament.
Nadal, the holder of tennis's remaining three Grand Slam titles (Wimbledon, the French Open and the US Open) beat Djokovic 7-6, 7-5 in the 2008 Queen's final before weeks later winning Wimbledon.
Now Djokovic hopes to tread a similar path, having insisted that "Wimbledon is the most important tournament of the year for me".
"The AEGON Championships is one of the nicest tournaments around," said Djokovic, who beat both Roger Federer and Murray on his way to winning a second Australian Open title.
"Rafa and I had an incredible match in the Queen's final in 2008 and it was the closest I ever got to a grass court title," the 23-year-old, twice a Wimbledon semi-finalist, added.
"Wimbledon is the most important tournament (of the year) for me, and I really want to do well at Queen's and at Wimbledon this year," explained Djokovic, who helped Serbia win the Davis Cup in December.
Queen's has a good track record in producing Wimbledon champions.
Nadal is one of six players to have won Queen's and Wimbledon in the same year with John McEnroe (1981, 1984), Jimmy Connors (1982), Boris Becker (1985), Pete Sampras (1995) and Lleyton Hewitt (2002) the others.
