Miguel Alcubierre (Born 1964) is a Mexican theoretical physicist. Born in Mexico City, he moved to Cardiff in 1990 to attend graduate school at the University of Wales. He received his Ph.D. in 1994.

After leaving Wales, he worked for a time at the Max Planck Institute for Gravitational Physics in Potsdam, Germany, where he developed new numerical techniques to describe the physics of black holes. He currently works at the National Autonomous University of Mexico (UNAM), where he conducts research in numerical relativity , the effort to employ computers to formulate and solve the physical equations first proposed by Albert Einstein.

Alcubierre is best known for his Alcubierre drive, a theoretical means of traveling faster than light that does not violate the physical principle that nothing can locally travel faster than light.
