Melda Ilgin was seated in an inflatable child's toy on Friday when strong winds caused her to drift away from the shore in the country's Canakkale province.
The yellow inflatable was carried further out to sea with the child still sitting atop it while her parents and others watching on the beach reacted with horror.
The Turkish coast guard was then called to the scene, and a man jumped from the rescue boat to carry her to safety, BGN News reported.
The winds had picked up on the beach, near the town of Kucukkuyo on the Aegean Sea, and were carrying her towards the Greek island of Lesbos, 10 kilometres away.
By the time the coast guard arrived, Melda was about a kilometre out to sea. They found her unharmed, still sitting in the inflatable device.
Dozens of onlookers gathered and watched as the baby girl was returned to her parents.
