This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States in July and August 2023. Tornado counts are considered preliminary until final publication in the database of the National Centers for Environmental Information. On average, there are 119 confirmed tornadoes in the United States in July and 81 in August.

The northern states nearer the Canadian border are most favored for tornadoes in July and August, including the Upper Midwest, the Great Lakes and the Northeastern states, due to the positioning of the summertime jet stream. Summer thunderstorms and tropical activity can also result in increased (mostly weak) tornado activity in the Florida Peninsula. In addition, there can also be occasional increases in the southern and eastern United States as a result of tornadoes from landfalling tropical cyclones should such occur, especially in August.

With 116 confirmed tornadoes, July saw near average levels of tornadic activity. No major outbreaks occurred during the month, although widespread severe weather with limited to scattered tornado activity occurred on most days. August saw well above average activity with 147 confirmed tornadoes and more significant tornadoes were confirmed during that time then in July especially in the climatologically favored Great Lakes and Northeast. However, no large outbreaks occurred during this month as well. Tropical tornadoes did not occur until the end of the month, when Tropical Storm Harold and Hurricane Idalia made landfall in the United States.
