'''Mount Usborne''' ({{langx|es|Cerro Alberdi}}) is a mountain on [[East Falkland]]. At {{cvt|705|m|ft}} above sea level, it is the highest point in the [[Falkland Islands]]. It is only {{convert|5|m|ft}} taller than [[Mount Adam, Falkland Islands|Mount Adam]], the highest peak on [[West Falkland]].

The mountain is referenced by [[Charles Darwin]] in Chapter 9 of ''[[Zoology of the Voyage of H.M.S. Beagle]]''. It is named after Alexander Burns Usborne,<ref>[http://www.usbornefamilytree.com/alexander1805.htm Alexander Burns Usborne]</ref> master's assistant on {{HMS|Beagle}}, the ship that took Darwin on his famous voyage.
