Charity Beat bullying said 26 out of the 59 cases reported in the national media over a period of eight years were definitely connected to bullying.
But research suggests the number of youngsters who killed themselves because of persecution could be as high as 78.
The official total number of children who killed themselves between 2000 and 2007 is 176.
Official data also recorded 1,769 suicides of 15 to 19-year-olds between the same period.
Beat bullying said this indicates that the total number of bullying-related adolescent suicides could be in the hundreds.
The charity found that every child suicide case related to bullying cited school as the main place of persecution.
Our Education and Children’s Bill in the autumn will put heads and teachers in control, giving them a range of tough new powers to deal with indiscipline, including bullying.
Education Secretary Michael Gove, commenting on the report
Of these, four cases also cited cyber bullying – where bullying takes place online, by email and on social networking sites – as a contributory factor.
The research also indicated a higher tendency of bully-related suicide among girls aged between 10 and 14, with 65% of such deaths involving girls.
The report was published to mark the second anniversary of the death of 13-year-old Sam Leeson, who hanged himself after being bullied physically and over the internet.
Sam’s mother, Sally Cope, said: "I know from personal experience just how devastating the consequences of bullying can be, and the void Sam’s death has left in my family.
"I urge the government to take action to fund anti-bullying work in schools and make the information regarding child suicides available so that organisations such as Beat bullying can work alongside them to prevent further deaths."
Georgia Wood says life became unbearable when she was bullied
Bullying victim Georgia Wood told Sky News she also considered taking her own life after she became a focal point of "hate" at secondary school.
"I had an argument with a girl and thought it would blow over the next day but it didn’t and more and more people got involved," she said.
"They started texting, emailing and ringing me at home so I didn’t feel safe anywhere… they also used social networking sites to say how much they hated me, I couldn’t turn a corner without being called something."
Georgia said that when her parents found out she was feeling suicidal they told her teachers.
"The school were very supportive… they literally saved my life," Georgia said.

Bullying is something one of my brothers suffered with and no doubt connected to the other problems he has faced in his life. Christopher Whitehead School in Worcester’s answer to the bullying problem straight from the principles mouth back then was “we don’t have bullying in the school”. Great shining example of why statistics are always wrong. Don’t admit there is a problem and obviously there isn’t one right? It pretty much ruined my brothers self confidence in himself and to this day has had problems. I myself remember being bullied for a year as a child but for different reasons as a child I was pretty violent and always in fights. I had an agreement with my parents when I went to a public school in Richmond that I wouldn’t get in any trouble so ended up being bullied the whole time I was there as I was unable to do anything about it. Reason I behaved was down to the fact my father was paying for my education there once we moved to Germany back to a government school within 3 days I had already beaten up the school bully and pretty much gone back to my usual routine. Nope I wasn’t a bully myself generally I would fight on the underdogs side not sure why just naturally did. Bit odd at school as I was good at sports and generally an ok student although never studied or done homework in the whole time I was at school. But the important factor here is getting back on topic and that bullying is pretty much ignored in society. I also see it growing because people seem to be more aggressive with each other these days and more inclined to go against someone doing well in something.
