Bank of Ireland is closing 88 branches.
The branches, due to close by the end of September, are mainly self-service which don't have a counter service.
It says they all have a post office within, on average, less than 500 metres.
The bank is entering into a new partnership with An Post to offer banking services at over 900 locations, with longer opening hours.
The branches to close in Dublin are:
- James Street
- Law Library
- Phibsboro
- Ballycoolin
- Killester
- Merrion Road
- Rathmines
- Ballyfermot
Francesca McDonagh, Group CEO of Bank of Ireland, says: "There's some in Dublin as well, it's not only outside of Dublin."
"It really is a reflection of usage and proximity to a neighbouring Bank of Ireland branch, and post office."
"We're not making a chance until September, so we wanted to give everyone advanced warning."
