Three prisoners took their own lives in Leeds jail last year as prison death rates continue to rise nationally.
The figures are based on notifications from the Ministry of Justice to charity, The Howard League for Penal Reform, which has compiled data on deaths in custody.
Nationally 82 prisoners took their own lives last year.
Data compiled by the Howard League for Penal Reform reveals they include 14 young adults aged between 18 and 24.
The figures for West Yorkshire showed that Leeds jail recorded three suicides, and Wakefield and New Hall near Flockton each recorded one suicide.
The figures come as the Howard League for Penal Reform and Centre for Mental Health are to embark on a joint programme of work on suicides in prison designed to find ways to end the death toll for good.
Frances Crook, Chief Executive of the Howard League for Penal Reform, said: “No-one should be so desperate whilst they are in the care of the State that they take their own life.
“The numbers hide the true extent of misery inside prisons and for families. It is particularly tragic that teenagers and other young people have died by their own hand in our prisons and we should all be ashamed that this happened.
“Hard-pressed prison staff have to save lives by cutting people down almost every day and without this the death toll would be even higher.
“It is evident that people are dying as a direct result of the cuts to the number of staff, particularly more experienced staff, in every prison.
“The government has chosen to allow the prison population to increase whilst it cuts staff, and that has led to an increase in people dying by suicide.”
