His wife Kirstin underwent a planned caesarean and gave birth to a baby girl on Monday.
The 35-year-old tweeted: "Thanks so much for all the well wishes. Mum and baby girl are happy and healthy. Happiest moment of my life hands down. #daddy #love."
Among those congratulating McDowell was fellow Northern Ireland golfer Rory McIlroy.
The world number one tweeted: "Congrats @Graeme_McDowell and @kristinstape on the birth of your beautiful baby girl! #DaddyGMac."
Former US Open champion McDowell has now decided to sit out his next tournament to spend some time with his family, following the new arrival.
"My caddie has been telling me all year 'You're not going to want to go to Boston', so I've decided to give myself the weekend off and just be with the family," he told the Golf Channel.
"Nice to be able to plan it that way."
