This paper summarizes our understanding of the geochemistry of sulfur in coal in the following areas: 1) abundance of sulfur in coals of major coal basins in the U.S., 2) distribution of sulfur in coal lithotypes and macerals, 3) characteristics and geochemical significance of sulfur-containing organic compounds, 4) sulfur isotopic studies relating to the sources of sulfur in coal, and 5) sedimentary environments controlling the geochemistry of sulfur in coal. The evidence suggests that the sulfur in low-sulfur coal (≤1% S) is derived primarily from parent plant material. In medium-sulfur (>1 to
