Ulysses Prentiss Hedrick (1870–1951) was an American botanist[1] and horticulturist.

He grew up in Northern Michigan near Harbor Springs, an experience recalled in his memoir The Land of the Crooked Tree, and was the brother of Wilbur Olin Hedrick.

He attended Michigan State Agricultural College (MSAC), now Michigan State University, receiving a Bachelor of Science degree in 1893 and a Master of Science degree in 1895.

[9] He continued to work at the Station, which he directed from 1928 onwards, until 1937, when he retired.

[1] During his lifetime, he authored or co-authored more than a dozen publications, which are "still frequently consulted", on the subjects of pomology and horticulture.
