At least 118 people convicted of terror offences were released from prison in the last four years, official figures show.
A total of 39 offenders convicted of "terrorist-related offences" were released on licence in 2012/13, with 44 released in 2011/12 and 35 in 2010/11, the Home Office figures for England and Wales showed.
Justice minister Shailesh Vara said figures for the latest year (2013/14) have not yet been published and so the total since 2010 could be higher if any were released this year.
Mr Vara said all prisoners convicted of terrorist-related offences are monitored on their release by the police, probation service and "other agencies".
The offenders are also subject to additional licence conditions to better manage any risk they pose.
Mr Vara released the figures taken from the Home Office TACT bulletin in response to a written parliamentary question from Tory Philip Davies (Shipley).
In his response, the minister wrote: "When released from prison, all prisoners convicted of terrorist-related offences released on licence are managed through Multi Agency Public Protection Arrangements (MAPPA).
"They will be risk assessed, monitored and supervised by probation, police and other agencies.
"Terrorist offenders subject to statutory probation supervision may also be required to comply with additional licence conditions to better manage any risk they pose."
