Introduction: The most effective way to close the treatment gap is to integrate mental health services with primary care to ensure that people receive mental health care they need in their place. Understanding providers' perceptions of evidence-based intervention have an undeniable role in improving their dissemination, implementation, and sustained use.
 Methods: This study was carried out to assess primary health workers' perception of the need of integrating mental health in primary health care settings in which 200 health workers from all the PHC, HP and UHC of the Kaski district were given a self-administered Likert scale having 5 points to assess the perception of health workers on need of integrating mental health in primary health care settings. The median score of Likert scale of perception of need was calculated then the chi square test was done to find the association which was followed by calculating adjusted odds ratio using binary logistic regression analysis.
 Results: Health workers who had gained information on mental health from course of study are 2.316 [CI:1.124-4.770] times more likely to perceive need of mental health integration into the primary health care setting and those who have provided mental health service are 2.801 [CI: 1.495-5.249] times more likely to be positive towards need.
 Conclusions: The majority of the health workers working at the primary health care level at Kaski district are positive towards mental health integration with the high number of health workers interested in receiving mental health training thus they should be provided with basic training in mental health to enhance their knowledge and skills for being able to provide mental health care to patients seeking help at the primary health care level.
