Seán Dineen (12 February 1944 – 18 January 2024) was an Irish mathematician specialising in complex analysis.

He attended St Mary's, the first secondary school for boys in Clonakilty, which his parents Jerry (Jeremiah) and Margaret Dineen had founded in 1938.

[2] Dineen was the first student of pure mathematics from UCC to travel to the USA to do his doctorate, where he did his coursework in the University of Maryland.

Dineen's work has principally been in the area of infinite dimensional complex analysis and the topological structure of spaces of Holomorphic functions.

His academic footprint includes 10 books and/or monographs, over 100 peer-reviewed research articles,[6] over 4000 citations,[7] 11 PhD students,[3] over 40 collaborators, and the organisation of numerous mathematical conferences and meetings.
