NatWest’s Oundle branch is one of 197 to close across the country.
The bank in Market Place will close on June 21, 2018, with NatWest saying branch usage is down by 40 per cent since 2014.
A decision sheet by Natwest said: “More and more people are choosing to do their banking online, with our mobile banking app, or over the phone.
“It’s more convenient to do it at a time and place that suits you, rather than come into branch.
“This means some branches are being used a lot less than they used to be.”
The closure means the nearest NatWest branch to those in Oundle will be in Corporation Street, Corby, with a branch in Cathedral Square in Peterborough the second closest.
The closure makes Barclay the only remaining High Street bank in the town.
NatWest customers will still be able to use banking services in the town’s Post Office, as well as those in nearby Barnwell and Warmington.
The closure comes as part of 259 Royal Bank of Scotland and NatWest branch closures in the UK, with an estimated 680 jobs going.
No other NatWests in the north of the county are among the branches to close announced today (Friday).
