Ultimately named after Glandore, a village in Co. Cork, but it seems likely that the name "Glandore" was first applied in Belfast to a house on Cavehill Road (BPU, 1894), before being extended to street-names in this neighbourhood. Glandore Gardens, along with Glandore Avenue / Drive / Parade, is part of a group of streets off Antrim Road with names beginning in Glan-. See also Glantrasna Drive, Glanleam Drive, Glantane Drive and Glanworth Drive / Gardens. 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'. However, the Irish name of Glandore is Cuan Dor, in which cuan means 'harbour'.
