The study investigated the level of youth participation in infrastructural development in Isin local government area of Kwara State, Nigeria. One hundred and five youths were randomly selected from seven rural communities, fifteen youths from each village. Data were collected with the aid of a questionnaire, which was analysed using frequency count and percentages. Chi-square analysis was used to test the hypothesis of significance between the socio-economic characteristics and the level of participation in infrastructural development. Findings revealed that 56.2% of respondents were within the age category of 21–30 years, 62.9% were male, and 60% were single, while 56.2% of the respondents had secondary school level education. The study revealed the various roles played by youths in participating in infrastructural development as well as the associated constraints which include finance, availability of materials, technical knowledge and time. Age, marital status, educational level and years of residence were found to be significantly related to the level of participation of youths in infrastructural development. The study recommended the adequate budget allocation to rural areas as well as intensive training and educative programmes for effective participative development.
