The King Block is a historic apartment house at 117 High Street, Barton, Vermont, United States.

The King Block is located just outside the downtown area of Barton, on the west side of High Street north of Eastern Avenue.

Due to the sloping nature of the lot, the south and west sides present the basement level as well.

The south-facing side facade is three bays wide, with a cross-gabled roof above that is pierced by a single shed-roof dormer.

The building exhibits typical design features of large tenements built in the state in the late 19th and early 20th centuries such as the multiple entry doors on the front façade and multi-level Colonial Revival style rear porch.
