The Night Tube service will come to SE1 for the first time when a 24-hour weekend service is introduced on the Jubilee line from 7 October.
All-night Tube services on the Central and Victoria lines started on 19 August.
"I was determined to get the Night Tube up and running as soon as possible, and I'm delighted the Jubilee Line will now begin on 7 October," said Sadiq Khan, Mayor of London.
"There was huge excitement at the launch of the Central and Victoria Lines last Friday, and it's already having a beneficial impact on our Night Time economy.
"Over 100,000 people used the Night Tube last weekend to get around London more quickly and safely.
"The launch of the Jubilee line will support thousands more workers like nurses, cleaners, and people who work in our bars and restaurants – many of whom currently take two night buses to get home. It will also serve some of our city's key venues, with The O2, Wembley Stadium and Stratford on route.
"I will continue to work closely with British Transport Police, TfL staff and Londoners across our city to ensure the roll-out of the Night Tube continues to be a success, and we unlock the full potential of London's exciting night time economy."
The Night Tube operates on Friday and Saturday nights.
