Farnhurst is an unincorporated community in New Castle County, Delaware, United States.

The site of two historic hospitals (one now gone) and a number of cemeteries, the community once had a post office, school, and rail station.

[3] The New Castle County Almshouse/Hospital also operated in Farnhurst from 1884 to 1933; these two large institutions were on adjoining plots.

[13] In 1912, Delaware courts ruled that the old soldiers living in the Farnhurst almshouse would be allowed to vote.

[20] The older cemetery on the grounds of the hospital and almshouse, which served as a potters field for New Castle County, was mostly obliterated in the 1950s/1960s by highway construction of the Farnhurst interchange providing access to the Delaware Memorial Bridge.

[27] Since 1978, this building has been the Howard J. Weston Senior Center,[28][29] now a part of the Wilmington Manor census-designated place.
