The President was scheduled to present the Jamnalal Bajaj Awards at a function in Mumbai on Thursday evening and also inaugurate the Sai Ashram at Shri Saibaba Temple at Shirdi, in Ahmednagar district, on Friday.
Asked why the President had cancelled his visit, a Rashtrapati Bhavan official told a news agency it was due to "Bal Thackeray's ill health".
The 86-year-old Thackeray has been suffering from breathing problems.
Anxious crowds have gathered outside Thackeray's residence Matoshri and his son, party executive president Uddhav Thackeray said the family had not lost hope.
Mumbai Police and other security agencies made tight security arrangements around Matoshri, in Bandra west.
Over 350 police personnel, plus the Rapid Action Force and other contingents, led by top officers, have deployed stringent security in the vicinity.
