A blue plaque was affixed to Ireton's birthplace at Church Lane in Attenborough, on 22 June 2011 by the Beeston and District Local History Society with the following text: "General Henry Ireton lawyer, confederate and son-in-law of Oliver Cromwell born here 1611 died Limerick 1651". The town of Ireton, Iowa, United States was named after Henry Ireton.

Ireton Avenue in Beeston near to Attenborough is named after General Ireton. Ireton Road in Market Harborough was also named after Henry Ireton, whilst Ireton Way is now a very straight part of the A142 between Ely and Chatteris, built by Ireton when he was commanding East Anglian forces as a causeway across the flooded Fens around the Ouse river to rush troops and supplies over when resisting Royalist attack from Lincolnshire and the Midlands.

There is also an Ireton Road in Colchester. This adjoins Honywood Road, named after Sir Thomas Honywood who led the Essex forces at the Siege of Colchester under the command of Thomas Fairfax.

His portrait continues to hang in the dining hall of Trinity College, Oxford.
