British number one Andy Murray will start his bid for a record fifth Queen's Club title with a first-round tie against former finalist Nicolas Mahut.
Murray won the Wimbledon warm-up event for a fourth time last year to equal the record tally set by John McEnroe, Andy Roddick, Lleyton Hewitt, Boris Becker and Roy Emerson.
Mahut, the current world number 49, who took on American Roddick at the 2007 Queen's final, stands between Murray and a potential second-round clash with Britain's Slovenia-born Aljaz Bedene.
Queen's is part of the ATP World Tour 500 series and finishes a week before Wimbledon, which runs from June 27 to July 10.
