The move, which will take effect from March 2006, is the latest in a series of changes in the last two years under the editorship of Lucy Yeomans.
Yeomans has repositioned the title as a modern fashion magazine. The rebrand also brings the title into line with the International Harper's Bazaar editions.
Tess Macleod-Smith, group publishing director of NatMags magazine division Luxury Group, said: "Harpers & Queen has been an incredibly successful enterprise and one of which I am immensely proud. The magazine has always had a very loyal readership and as the magazine evolved the circulation has grown.
"We hope this move towards the international brand will further widen our appeal among new readers but initially it is integral that we maintain the loyal readership that already enjoy the magazine each month."
Harpers & Queen posted its highest circulation figure since 1988 in the most recent magazine ABC report. According to the ABC, active sales increased by 3.7% year on year to 100,102 copies.
