守貞教育,又称婚前守貞教育、純潔教育、唯禁欲性教育(英語:Abstinence-only sex education),是性教育的一種形式,其会教育学生不要進行發生婚姻以外的性行為,並以负面角度形容发生婚前性行為及女性進行墮胎后的后果。它一般不會像綜合性性教育般教授学生有關预防性病、安全性行為及避孕般的知識。

Abstinence-only curricula have been found to contain scientifically inaccurate information, distorting data on topics such as condom efficacy, and promote gender stereotypes. An independent evaluation of the federal program, several systematic reviews, and cohort data from population-based surveys find little evidence of efficacy and evidence of possible harm.
