Abstract: Recreational facilities provide opportunities for physical activity, relaxation, social interaction, stress reduction, and recovery, which may contribute to enhanced productivity among staff and students in tertiary institutions. However, inadequate facilities, poor maintenance, limited accessibility, and competing academic and work demands may constrain their utilisation. This study assessed recreational facilities utilisation and productivity in selected tertiary institutions in Rivers State, Nigeria. A cross-sectional survey design was adopted, and data were collected from 367 academic staff and students using a structured questionnaire and facility assessment checklist. The findings indicated that recreational facilities were available across the institutions, although their distribution and functional adequacy varied. Swimming pools and specialised recreational facilities were limited, while deficiencies were observed in maintenance, cleanliness, and equipment functionality. Accessibility and adequacy of facilities were moderate (grand mean = 2.51). Recreational facilities utilisation was also moderate, with 65.1% of respondents using facilities at least weekly. Availability (M = 3.21), personal interest (M = 3.08), accessibility (M = 2.97), and safety/security (M = 2.89) were the major factors influencing utilisation. The leading constraints were limited time/academic workload (M = 3.42), inadequate facilities (M = 3.28), poor maintenance (M = 3.15), and lack of equipment (M = 3.09). Overall productivity was high (M = 3.05). Recreational facilities utilisation was significantly and positively correlated with productivity (r = .412, p < .001) and significantly predicted productivity (β = .386, t = 5.26, p < .001), explaining 18.3% of its variance (R² = .183; F = 27.64, p < .001). No significant differences in productivity were observed by respondent category, sex, institution, age, or years of service/study (p > .05). The study concludes that recreational fac
