The United States National Snipe Championship is the annual national championship for sailing in the Snipe class. It is among the oldest One-Design class championships in the United States. Between 1934 and 1947 it was considered the SCIRA World Championship, with the winning skipper receiving the Commodore Hub E. Isaacks Trophy, but as the event became international after World War II, SCIRA's commodore Charles Heinzerling created a separate trophy for the USA champion and since then the winning skipper is awarded the Commodore Charles E. Heinzerling Trophy, and the winning crew is awarded the Portage Lakes Yacht Club Trophy.
