This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States from April to May 2023. Tornado counts are considered preliminary until final publication in the database of the National Centers for Environmental Information. Based on the 1991–2020 average, about 155 tornadoes occur in the United States in April, while 276 tornadoes occur in May. Activity also tends to spread northward and westward in April compared to the cooler winter months and the Midwest and Great Plains tend to see increased activity, although the relative maxima remains in the southern states. The shift northward and westward continues into May, as the maxima moves into the Midwest and the Great Plains as the springtime jet stream patterns tend to occur farther north (while the South begins to see decreasing activity), while the potential for tornadic activity also increases in the Northeastern United States.

Overall, April saw near average levels of activity in the United States with 160 tornadoes being confirmed. The start of the month saw very active tornadic activity, with over 60 tornadoes during the first five days of the month, with the first coming as the second day of an outbreak that began on March 31. However, moisture return became more limited after that, and tornadic activity went dormant for a few days. Some severe weather outbreaks did occur at the start of the middle of the month, but these outbreaks mainly produced very large hail or damaging winds instead of tornadoes and most of the tornadoes were weak. However, more consistent scattered to widespread tornadic activity began in the second part of the month, which included a moderate-sized outbreak between April 19–20. On the other hand, the tornado count for May was significantly below average with 171 tornadoes, most of which were weak. May featured steady activity throughout the month (and no major outbreaks) with only a brief period of enhanced activity towards the middle part of the month. It was the fourth straight year that no violent tornadoes touched down in May as well as the second time in three years that no EF3+ tornadoes were confirmed.
