The Trans-Jordan Frontier Force Long Service and Good Conduct Medal was an official United Kingdom award relating to the Emirate of Transjordan, which was a British protectorate.

It included cavalry, infantry, camel and mechanised troops with, before the Second World War, a strength of nearly 1,000 men.

It rewarded NCOs and men of the Trans-Jordan Frontier Force who had completed 16 years exemplary service.

The obverse bears the effigy of King George VI with, around the perimeter, the legend 'GEORGIVS VI D:G:BR:OMN:REX ET INDIAE IMP:' The reverse is inscribed 'FOR LONG SERVICE AND GOOD CONDUCT' over four lines with, around the circumference, the words 'TRANS-JORDAN FRONTIER FORCE'.

[4] The 32mm wide ribbon is crimson with a central green stripe, the same as for the West African Frontier Force and King's African Rifles Long Service and Good Conduct Medals.
