Bergelmir er en af planeten Saturns måner: Den blev opdaget den 4. maj 2005 ud fra observationer foretaget af et hold astronomer fra Hawaiis Universitet under ledelse af Scott S. Sheppard mellem den 12. december 2004 og den 9. marts 2005, og fik lige efter opdagelsen den midlertidige betegnelse S/2004 S 15.
Bergelmir har retrograd omløb om Saturn, dvs. den populært sagt "kredser den gale vej rundt".

Cropped version of N00164957.jpg, showing the brightest object in the frame - which may or may not be Bergelmir, moon of Saturn Raw image N00164957.jpg was taken on October 30, 2010 and received on Earth November 02, 2010. The camera was pointing toward BERGELMIR, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2011.
