You're likely thinking of Orion's Belt, which consists of three bright stars in a row: Alnitak, Alnilam, and Mintaka. They are easily visible in the eastern sky during the winter months in the Northern Hemisphere.

However, it's important to note that the exact position of constellations in the sky changes throughout the year due to the Earth's rotation and orbit. So, while Orion's Belt is prominent in the eastern sky during winter, it will be in other parts of the sky at other times of the year.
