The attack happened on Tuesday at Robb Elementary School in the city of Uvalde.
The school has an enrollment of just under 600 students.
Governor Greg Abbott said the shooter was an 18-year-old man who lived in the city and entered the school with a handgun.
In a statement, Governor Abbott said the state was "grieving for the victims of this senseless crime".
He also thanked "the courageous first responders" who worked to secure the school.
