To increase performance, manufacturing firms in Kenya formulate and implement growth strategies. However, past studies in Kenya have not examined the effect of growth strategies on the performance of food manufacturing firms. The objective of this study was to determine the effect of growth strategies on the performance of food manufacturing firms in Nairobi County, Kenya. A proportionate sample of 71 firms representing seven sub-sectors of food manufacturing firms in Nairobi County was used. Primary data was collected from 64 firms using structured questionnaire administered to the Managers of the firms. The results revealed positive effect of growth strategies on organizational performance. The paper concluded that firms implementing growth strategies achieve higher organizational performance.
