Etinilestradiol (EE) adalah obat estrogen yang digunakan secara luas dalam pil kontrasepsi, dalam campuran dengan progestin..[10][11] Sebelumnya, EE digunakan untuk berbagai indikasi, seperti pengobatan gejala menopause, kelainan ginekologi, serta kanker sensitif hormon tertentu. Obat ini biasanya diminum tetapi kadang juga dihantarkan melalui kulit dengan pelekat transdermal, atau melalui gelang vaginal.[10][12]
