Named after Glanworth, a town, townland and parish in Co. Cork. Glanworth Drive, along with Glanworth Gardens, is part of a group of streets off Antrim Road with names beginning in Glan-. See also Glandore Avenue / Drive / Gardens / Parade, Glanleam Drive, Glantane Drive and Glantrasna Drive. All of these are place-names in the province of Munster, but beyond this they have little in common. Glan- is usually an anglicisation of the Irish word gleann, 'valley'.
"Resolved: That on the application of Messrs McLaughlin & Harvey Ltd., the name "Glanworth Drive" be approved for a new street on their property, situate off Glansdowne and Skegoniel Avenues". (9th May 1922)
