The Rail, Maritime and Transport (RMT) union has suspended a planned 24-hour Tube strike, which was set to begin tomorrow evening.
Despite Tuesday's industrial action being cancelled, further strikes that are due to take place in February are due to still go ahead, the union has announced.
The dispute between the unions and London Underground revolves around pay and the all-night Tube service.
General Secretary Mick Cash said: "RMT's executive has agreed to suspend tomorrow's action over pay and night Tube to allow for further consideration and consultation on the current offer.
"The union makes it clear that we remain in dispute and the strike action scheduled for February remains on.
"RMT also remains in dispute over station staffing and the week of action on that issue, scheduled to begin from the seventh of February, also remains on and the union is finalising the details for the continuation of that industrial campaign and the on-going fight over the threat to jobs, services and safety."
Aslef, TSSA and Unite had already pulled out of tomorrow's industrial action.
