Lake Bonney (Antarctica)
Lake Bonney (
) is a saline lake with permanent ice cover at the western end of Taylor Valley in the McMurdo Dry Valleys of Victoria Land, Antarctica.

It is  long and up to  wide. A narrow channel only  wide (Lake Bonney at Narrows) separates the lake into East Lake Bonney () and West Lake Bonney ().

To the north and south of the lake lie peaks that are over  above sea level, and the Taylor Glacier is positioned to the west of the lake. It is  deep and is perpetually trapped under  of ice.

It was first visited by the British National Antarctic Expedition of 1901-1904. It was named by the Robert Falcon Scott expedition of 1910-1913, for Thomas George Bonney, professor of geology at University College London, England from 1877 to 1901.

Lake Bonney is one of the main lakes studied by the National Science Foundations, McMurdo Long Term Ecological Research site.

Starting in 2007 NASA is funding an autonomous submersible robot called ENDURANCE to explore the water volume of the lake to study its shape and ecology. The robot is built by Stone Aerospace, who also developed the DEPTHX submersible. The Endurance Project is led by Peter Doran with Bill Stone and John Priscu among the co-investigators. Scientists have discovered an ancient ecosystem beneath the Taylor Glacier, next to Lake Bonney. This ecosystem survives by transforming sulfur and iron compounds for growth.

The work is seen as a stage in developing an autonomous submersible robot that could explore the ocean on Jupiter's moon Europa.

The green algae Chlamydomonas priscuii is endemic to this lake.

Tributaries
Lake Bonney is fed by a number of meltwater streams:
 Bartlette Creek
 Bohner Stream 
 Doran Stream (feeding Priscu Stream)
 Lawson Creek
 Lizotte Creek
 Lyons Creek
 Mason Creek
 Priscu Stream (the longest, )
 Red River
 Santa Fe Stream
 Sharp Creek
 Vincent Creek
