Edward Sean Linden (born John Edward Glackin; 5 May 1935) is a Scottish poet, literary magazine editor and political activist. From 1969 to 2004, he published and edited the poetry magazine Aquarius, which, according to The Irish Post, made him "one of the leading figures on the international poetry scene". The journal was significant in the growth of British, Irish and international poets, and has been described as Linden's "crowning gift to literature — the nurturing and developing of poetic talent".
