Abstract: This paperwork discussed the influence of work engagement on organisational citizenship behaviour among Malaysian police officers. Work engagement is measured by three dimensions which are dedication, vigor and absorption; while organisational citizenship behaviour is measured by five dimensions which are altruism, conscientiousness, civic virtue, courtesy and sportsmanship. Findings showed that Malaysian police officers have high level of work engagement (M=5.69, SD=0.911) and organisational citizenship behaviour (M=5.58, SD=0.77). Meanwhile, their work engagement does influence the organisational citizenship behaviour (R²=0.425) in which the dimension of dedication is the most influential one (β = 0.368, p < 0.05). This finding is beneficial in assisting organisations recruitment process in the future.
