The Friends’ Christmas raffle raised nearly £3,000 - around three times the amount achieved in recent years.
The raffle was drawn in the Out Patients building at the Hospital of St Cross on Friday.
Volunteers helped raise £2,727 for the charity.
Doris Froggatt, who organised the raffle and co-ordinates the charity’s collections, said: “I am chuffed to bits. The support we have had this year has been overwhelming.
“I am sure that lots of things have contributed to this success.
“The great prizes donated by Jamesway Travel, M&M Jewalers and Sainsbury’s Local in Clifton Road which were highlighted on the tickets must have boosted sales, as did the fact that many of our supporters, including the major prize donors, the Mayor of Rugby and Abbey News, sold lots of tickets on our behalf.”
She added: “I would like to say a great big thank you to everyone who helped and especially the Coventry Building Society who printed the tickets.”
The money raised will go towards the Diamond Jubilee Appeal which aims to improve the busy blood taking unit at the hospital.
On Saturday Rugby Male Voice Choir held its annual Charity Christmas Concert in aid of the Friends of St Cross.
More than 100 people enjoyed a mix of Christmas carols and choral pieces.
The choir will hold another event in aid of the Friends - the Mayor’s Charity of the Year - in April.
Heather Green, chairperson of the Friends, said: “Our Diamond Jubilee Appeal has received a tremendous response from the people of Rugby and we look forward to this continuing in 2015 which is our actual Jubilee year.
“We have lots of plans for special events which are taking shape and will be published on our website when the details are confirmed.
“In the meanwhile, we would like to thank everyone for their support to date and look forward to hearing about any plans that members of the public, clubs, societies and businesses have for helping us to break through our initial target of raising at least £60,000 for the Appeal.”
