Sergio Santos Hernández (born November 1, 1963) is an Argentine professional basketball coach.
Hernández coached the senior men's Argentine national team from 2005 to 2010. He succeeded Rubén Magnano in the position, and was the team's head coach at the 2008 FIBA Diamond Ball (where the team won the gold medal), the 2008 Summer Olympic Games (where the team won a bronze medal), and at the 2010 FIBA World Championship (where Argentina finished in 5th place).
After his contract to coach the Argentine national team expired in 2010, Hernández did not accept the 4–6 years renewal offered by the Argentine Basketball Federation, therefore ending his tenure as the national team's head coach. He did, however, return to the team as an assistant coach for the 2012 Summer Olympic Games.
