Frankton Junction is the name of the canal junction where the Montgomery Canal terminates and meets the Llangollen Canal at Lower Frankton, Shropshire, England.

The Shropshire Union Railways and Canal Company was a Company in England, formed in 1846, which managed several canals and railways. It intended to convert a number of canals to railways, but was leased by the London and North Western Railway (LNWR) from 1847, and although they built one railway in their own right, the LNWR were keen that they did not build any more. They continued to act as a semi-autonomous body, managing the canals under their control, and were critical of the LNWR for not using the powers which the Shropshire Union Company had obtained to achieve domination of the markets in Shropshire and Cheshire by building more railways.
