This study assessed the effects of strategic leaders’ cognitive qualities on lecturers’ performance with a reference to Jaramogi Oginga Odinga University of Science and Technology, Kenya. A target population of 144 lecturers was used and a sample size of 106 lecturers obtained who responded to questionnaires. Mixed method of qualitative and quantitative approaches was applied.  The results showed that strategic leaders’ were elected and appointed with a consideration on cognitive qualities at 43.4%.  Also lecturers considered cognitive qualities as important and essential in the field of academics.  This was seen to be essential in developing and formulating strategies, resolving problems and using intellectual skills to encourage and mentor lecturers on research, publishing in refereed journals, developing market demand driven programmes and facilitated completion of PhD students within the stipulated period of study.  The findings further revealed a statistically significant relationship between strategic leaders’ cognitive qualities and lecturers’ performance (R2 = 0.187; p<0.001) and coefficients were all statistically significant. Statutes governing appointment of strategic leaders need to highlight qualities required when appointing and electing strategic leaders to holistically understand administrative issues and conform to the requirements of leadership requirements.
