New York State Route 28B (NY 28B) was a state highway in Oneida County, New York, in the United States. The route served as a connector between NY 287 (now NY 365) in the village of Prospect and NY 12 and NY 28 in the village of Remsen. It was assigned in 1935 and removed in the mid-1960s, at which time most of the route became New York State Route 920V, an unsigned reference route. The alignment of NY 28B was originally part of legislative Route 26 and later Route 25 in the early 20th century.
