Kepler-296b is an s-type exoplanet located in the binary star system Kepler-296. All 5 planets in this system orbit around the primary star.

It has been classed as a hot superterran.

It was discovered by the Kepler space telescope in 2014 using the transit method and was originally classed as a planet candidate, but during a study{{Cite web|title=Astronomers Catalog Planets That May Be Earthlike|url=https://www.jpl.nasa.gov/news/astronomers-catalog-planets-that-may-be-earthlike|access-date=2021-03-17|website=NASA Jet Propulsion Laboratory (JPL)|language=en}} by members of the NASA Ames Research Center on two other planets in the Kepler-296 system, Kepler-296f and Kepler-296e, they were able to confirm that Kepler-296b is an exoplanet with "more than 99% confidence".
