This study aims to identify the knowledge and attitude towards emergency contraception among nursing students from a public university in Goiás - a state in Brazil. A descriptive and analytical research methodology with a quantitative approach was used, applying, from February to May 2011 a questionnaire on the sexual knowledge and attitude of students regarding emergency contraception. 178 students participated in the study. Knowledge was confirmed through the high frequency of correct answers to the questions, especially those concerning the correct time and the instructions for use (between 86% - 96%). Although many students use this method, there are still some doubts about the mechanism of action, side effects and access availability (frequency of correct answers lower than 50%). We noticed the need to develop educational policies that encourage the promotion of sex education in schools and universities.
