"Sleepy Joe" is a nickname that has gained widespread recognition, particularly among critics of Joe Biden, the 46th president of the United States. This moniker was first introduced by former President Donald Trump in 2019, during the early stages of the 2020 presidential campaign. Trump, known for his colorful and often derogatory nicknames for political opponents, used "Sleepy Joe" to question Biden's energy levels, mental acuity, and fitness for office.
