In this note, we introduce a generalisation of the concept of Engel elements called \(p'\)-Engel elements and investigate some basic properties of \(p'\)-Engel elements together with four related sets in a finite group. We obtain some characterisations of finite p-nilpotent groups, soluble groups and minimal non-p-nilpotent groups by use of \(p'\)-Engel elements.
