Gender equality is a fundamental human right and vital to accelerate global progress towards several Sustainable Development Goals (SDGs). Adolescents' involvement is essential to achieve such equality and SDGs to develop peaceful sustainable societies. However, there are limited data especially from developing countries such as India to plan gender equality related programmes targeted at adolescents. : We conducted a cross-sectional survey to assess gender equality related knowledge, attitudes, and behaviours among 16 to 19 year-old adolescents from sixty villages of the Maharashtra state of India. : Data from 1306 respondents (667 females and 639 males) showed a mean score of 30 out of 44, suggesting an overall moderate gender equality score in rural adolescents. The majority of girls (68.3%) were in the high scoring group, whereas the majority of boys were in the moderate group (60.3%). Regression analysis showed that responses from boys were associated with lower scores compared to responses from girls by five points (adjusted β-coefficient: -4.99, 95%CI: -5.85 to -4.12, p<0.001). : Our findings suggest that there is a need to involve adolescents with a major focus on boys to improve gender equality in rural areas of Maharashtra. This will help introduce concepts of equality from an early age to educate boys, empower girls, and address gender-based discrimination and violence against girls and women.
