Tertiary Education Trust Fund (TETFUND) was established by Federal Government of Nigeria to tackle the problem of inadequate funding of tertiary institutions which had been a major obstacle to the achievement of sustainable developments in these institutions. This study therefore examined the impact of TETFUND interventions on sustainable development goals (research and academic growth and continuous provision of instructional materials and laboratory equipment) Olabisi Onabanjo University, Ogun State, Nigeria. Descriptive survey research design was adopted and qualitative data were collected using a questionnaire to elicit information from a total number of 250 respondents from total population of 1,723 staff of the university. From the sample size, 128 (56%) were male while 122 (54%) were female. Data collected were analyzed using regression analysis to test all the hypotheses at 0.05 level of significance. Findings revealed that TETFUND interventions have significant impact on sustainable development goals of Olabisi Onabanjo University. It is therefore recommended that Federal Government should step up efforts to ensure that tertiary institutions (federal and state owned) are adequately funded through TETFUND and also do more in the area of human resource development for the research and academic growth of these institutions.
