In [[telecommunication]]s, '''trunking''' is a technology for providing network access to multiple clients simultaneously by sharing a set of circuits, carriers, channels, or frequencies, instead of providing individual circuits or channels for each client. This is reminiscent to the structure of a tree with one trunk and many branches. Trunking in telecommunication originated in telegraphy, and later in telephone systems where a '''trunk line''' is a [[communications channel]] between [[telephone exchange]]s. 

Other applications include the [[trunked radio system]]s commonly used by police agencies.<ref>{{cite journal |last1=Sharp |first1=D.S. |last2=Cackov |first2=N. |last3=Laskovic |first3=N. |last4=Shao |first4=Qing |last5=Trajkovic |first5=L. |title=Analysis of public safety traffic on trunked land mobile radio systems |journal=IEEE Journal on Selected Areas in Communications |date=2004 |volume=22 |issue=7 |pages=1197–1205 |doi=10.1109/JSAC.2004.829339 |s2cid=4912845 |url=https://ieeexplore.ieee.org/document/1327644}}</ref> 

In the form of [[link aggregation]] and [[VLAN tagging]], trunking has been applied in [[computer networking]].
