Bloomfield is a home rule–class city in Nelson County, Kentucky, in the United States.

The community on the east fork of Simpson Creek originally grew up on sites purchased from Leven Powell's 2,000-acre (810 ha) land grant, which he received from the state of Virginia in 1779 and surveyed in 1781.

Dr. John Bemiss of Rochester, New York, had settled in the area in 1799;[5] in 1817, he laid out the town and renamed it Bloomfield, supposedly after his wife's maiden name (Bloomer) and his daughter's married name (Merrifield).

[1] Bloomfield's economy has always been agriculturally based, but there was a flour mill and a tobacco auction house in the 19th century.

The Newell B. McClaskey House and plantation was built in 1835, and is now listed on the National Register of Historic Places.

[5] Bloomfield is located on the East Fork of Simpson Creek (part of the Salt River watershed).

[9] The Library features several public computers, a kids program with multiple activities for teens and children, and lots of decor, furniture, and books.
