The given name Jashawn has its origins in African American culture, emerging in the late 20th century as a variation of the more traditional name Shawn or Sean. It is believed to have been derived from the Irish name Seán, which itself comes from the Hebrew name Yohanan, meaning "God is gracious."

While the name Jashawn does not have a long historical record, it is believed to have been created by adding the prefix "Ja" to the name Shawn. The "Ja" prefix has been used in various African American names, often as a nod to the Jamaican or West Indian influence in some communities.

One of the earliest known bearers of the name Jashawn was Jashawn Parker, a professional basketball player born in 1992 in Philadelphia, Pennsylvania. Parker played college basketball at the University of South Carolina before being drafted by the Utah Jazz in the NBA.

Another notable Jashawn was Jashawn Sheffield, a football player born in 1996 in Atlanta, Georgia. Sheffield played college football at Texas Tech University and was later signed by the Houston Texans as an undrafted free agent in 2019.
