President Maithripala Sirisena has been extending the emergency on the 22nd of each month since the April 21 attacks on three hotels and three churches.
However, his office confirmed that Sirisena had not extended it for another term and thereby allowed the emergency to end on Thursday.
"The president did not issue a fresh proclamation extending the emergency by a further period," an official source said.
The official government printer also confirmed that there was no notification reimposing the state of emergency, which gives sweeping powers to police and security forces to arrest and detain suspects for long periods.
The government used the emergency as it tightened security across the country and hunted members of a local jihadist group which was held responsible for the attacks and which claimed allegiance to the Islamic State group.
