Accurate estimations of race and sex are essential tools in forensic anthropology. The pelvic bones are the most accurate bones from which sex can be determined, where ischiopubic index and subpubic angle are important parameters in these bones. The objective of our study is to determine ischiopubic index and subpubic  angle in Egyptian males and females and compare them with  other populations.  Antero -posterior radiographs of 120 adult males and females (aged from 18 to 70 years) were studied for measurement of the pubic length, the ischial length and subpubic  angle. Results: the mean of  pubic length, ischial length, ischiopubic index and subpubic  angle in  Egyptians males were 72.4 mm, 80.6 mm,  86.3 and  102.4° respectively. The mean of  pubic length, ischial length, ischiopubic index and subpubic  angle in  Egyptians females were 83.5 mm, 74.5 mm, 103.5  and  141.2° respectively. The mean of pubic length was significantly increased in females than males in the (p < 0.05), while the mean ischial length was significantly higher in males than females (p < 0.05), the mean ischiopubic index was significantly higher in females than males (p < 0.05), while the mean of subpubic angle in females was significantly higher than males
