Pictures: The Church of England
Lucas Salinger (pictured below), who attends Potten End Church of England School near Berkhamsted in Hertfordshire, saw-off competition from more than 1,000 other youngsters.
Head teacher Andrew Morris said: "I am extremely proud that a member of my school has won the competition, out of so many entries.
"Lucas is a thoughtful and talented young man who thoroughly deserves recognition for his hard work on the logo.
"I so am pleased that Lucas has incorporated the cross design that hangs in our church in Potten End."
With official celebrations planned between 10th and 12th June to mark Her Majesty's 90th birthday, The Church of England invited children at Church schools to create a logo for the occasion.
The schedule of events includes a thanksgiving service at St Paul's Cathedral in London, a Birthday Parade on Horse Guards Parade and a street party in The Mall.
It's hoped church events will be integrated into local community celebrations taking place that weekend.
The Rt Hon Sir Tony Baldry, Chair of the Church Buildings Council, said:
"It is wonderful that the visual marker that will unite these events has been designed by a young pupil at a Church school.
"Many churches have already begun making plans. We hope that our web hub on the ChurchCare website will be a source of inspiration and support in the lead up to June."
