The Great Tit (Parus major) is a passerine bird in the tit family Paridae. It is a widespread and common species throughout Europe in any sort of woodland. It is resident, and most Great Tits do not migrate. In the past this species was considered a ring species with several subspecies covering a wide distribution, but these have now been separated.

The breeding population of Great Tits in the city of Sheffield, UK (a city of half a million people), has been estimated at 17,164 individuals.
The Great Tit was unsuccessfully introduced into the United States; birds were set free near Cincinnati, Ohio between 1872 and 1874 but failed to become established. Birds later introduced to the Almaty Province in what is now Kazakhstan in 1960-61 and have become established, although present status is unclear.

The Great Tit is a popular garden bird due to its acrobatic performances when feeding on nuts or seed. Its willingness to move into nest boxes has made it a valuable study subject in ornithology, and it is one of the best studied birds in the world.
However, human habitat also has an effect on the Great Tit. The song of the Great Tit has been observed to change in noise polluted urban environments. In areas with low frequency background noise pollution, the song has a higher frequency than in quieter areas.
