The 3rd/4th Cavalry Regiment is an armoured regiment of the Australian Army, and is third in order of precedence in the Royal Australian Armoured Corps. The regiment was formed in 1981 through the amalgamation of the 3rd Cavalry Regiment and the 4th Cavalry Regiment. Currently there is only one squadron in existence, 'B' Squadron, which is currently part of the 3rd Brigade and is based in Townsville, Queensland. Recent deployments have included Iraq, Afghanistan and Timor Leste. The unit operates the Bushmaster Protected Mobility Vehicle (PMV). In December 2014, the squadron's personnel will be transferred to the 2nd Cavalry Regiment as part of that unit's establishment as an Armoured Cavalry Regiment, while the squadron will be transferred to Australian Army Reserve and reassigned to the 11th Brigade.

The 3rd Cavalry Regiment was formed in beginning of 1967 when, as a result of a re-organisation of the units of the Royal Australian Armoured Corps, the 1st Armoured Personnel Carrier Squadron which was serving in Vietnam at the time, was renamed as 'A' Squadron, 3rd Cavalry Regiment. At the same time 'B' Squadron, 3rd Cavalry Regiment was formed in Australia to provide a follow-on force and relieve 'A' Squadron at the end of their tour. Equipped with the M113A1 armoured personnel carriers (APCs), its initial strength in Vietnam was 10 officers and 107 men. Both 'A' and 'B' Squadrons of the 3rd Cavalry Regiment would continue this extensive service throughout the remainder of Australia's involvement in Vietnam as part of the 1st Australian Task Force (1 ATF), with a squadron of the regiment operating there for nearly the next six years.
