J. T. S. Brown is a Kentucky bourbon whiskey produced by the Heaven Hill Distillery company.

The brand was named after John Thompson Street Brown Sr., who together with his half-brother George Garvin Brown (1846–1917), opened a wholesale liquor business on Whiskey Row, Main Street, Louisville in 1870.

It later became the Brown-Forman corporation, and ownership of the brand eventually devolved to Heaven Hill, a company founded in 1935.

After the fire, distilling capacity in the Louisville area was temporarily made available as a goodwill gesture by the Brown-Forman corporation, and Fortune Brands also assisted with some capacity at its Jim Beam distillery.

Although Heaven Hill no longer operates a distillery at its company headquarters in Bardstown, its rick houses for aging and its bottling operations were kept in Bardstown, about 40 miles away from the current distillery.
