Police officers said they were called at approximately 2.34am local time (07:34 GMT) about a shooting outside Billiards and Bowling Alley in Houston where a private party of around 40 including Takeoff had been taking place.
Takeoff was found dead at the scene and two other individuals, a 23-year-old male and a 24-year-old female, were taken to the hospital with non-life-threatening injuries.
Houston police chief Troy Finner has said he has received many calls praising Takeoff as a “great young man”.
Mr Finner said: “Sometimes the hip hop community gets a bad name and I know, evident from this city and people who I have a personal relationship with, a lot of great people in our hip hop community and I respect them.
“But back to Takeoff. I got many calls from Houston and outside of Houston, and everyone spoke of what a great young man this is, how peaceful he is, what a great artist. And I’m calling up on everybody, hip hop artists in Houston and around the nation, we got to police ourselves.”
