• Kenneth Geddes Wilson – United States (1936–2013) Nobel laureate. He developed the theory of renormalization group, used to understand phase transitions.
• Robert Woodrow Wilson – United States (born 1936) Nobel laureate. He and Arno Penzias discovered the cosmic microwave background radiation.
• David J. Wineland – United States (born 1944) Nobel laureate. He developed methods to cool and trap ions using laser light.
• Edward Witten – United States (born 1951). A leading theoretical physicist who works on string theory and quantum field theory.
• Chien-Shiung Wu – United States (1912–1997). A groundbreaking experimental physicist who disproved the law of parity conservation in weak interactions.

• Chen Ning Yang – China (born 1922) Nobel laureate. He and Tsung-Dao Lee showed that parity is not conserved in weak nuclear interactions.
• Thomas Young – UK (1773–1829). He made important contributions to optics, including the wave theory of light, and studied elasticity.
• Hideki Yukawa – Japan (1907–1981) Nobel laureate. He predicted the existence of the pion, a particle that mediates the strong nuclear force.

• Pieter Zeeman – Netherlands (1865–1943) Nobel laureate. He discovered the Zeeman effect, which is the splitting of spectral lines in a magnetic field.
• Anton Zeilinger – Austria (born 1945) Nobel laureate. He shared the Nobel Prize for his work on quantum entanglement and quantum information science.
• Yakov Borisovich Zel'dovich – Russia (1914–1987). A brilliant astrophysicist and cosmologist who made contributions to nuclear physics and the Big Bang theory.
• Frits Zernike – Netherlands (1888–1960) Nobel laureate. He invented the phase-contrast microscope, which allows us to see transparent biological samples.
• Peter Zoller – Austria (born 1952). A theoretical physicist known for his work on quantum optics and quantum information.
• George Zweig – United States (born 1937). He independently proposed the existence of quarks.
