Who was the first published poet in American colonies?

It's difficult to definitively say who the first published poet was in the American colonies because early American literature was often published anonymously or under pseudonyms.

However, Anne Bradstreet is widely considered to be the first significant American poet whose works were published. Her collection, "The Tenth Muse Lately Sprung Up in America," was published in London in 1650.

While there were likely other poems published before Bradstreet's work, hers was the first collection to be published and gain significant recognition. It's important to remember that the concept of "American" identity was still developing at this time, and many early American poets were influenced by English literary traditions.
