Stephenson 2-11 (St 2-11), également connue sous le nom de Stephenson 2 DFK 49 ou RSGC2-11, est une étoile supergéante rouge de la constellation de l'Écu de Sobieski. Elle se situe dans l'amas ouvert (en), située à environ 6 kpc soit 20 000 années-lumière de la Terre (distance de l'amas (en)).

Stephenson 2 DFK 49 or Stephenson 2-11 is a putative post red supergiant star in the constellation Scutum. It is located in the massive open cluster Stephenson 2. It is possibly one of the largest known stars with radius estimates ranging from almost 1,000 solar radii to 1,300 solar radii. If the upper estimate is correct, then Stephenson 2 DFK 49 has a volume 2.2 billion times that of the Sun. If it was placed at the center of the Solar System, its photosphere will potentially approach or engulf Jupiter's orbit. It loses mass at a very high rate, resulting in large amounts of Infrared excess.
