Bosnian-gauge railways are railways with track gauge of 760 mm. These were found extensively in the former Austro-Hungarian Empire as a standardised form of narrow gauge. The name is also used for lines of the same gauge outside Bosnia, for example in Austria. Similar track gauges are the 2 ft 6 in and 750 mm gauge.

In rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks.
