In human anatomy, the inguinal region refers to either the groin or the lower lateral regions of the abdomen. It may also refer to:

• Conjoint tendon, previously known as the inguinal aponeurotic falx, a structure formed from the transversus abdominis insertion into the pecten pubis
• Granuloma inguinale, a bacterial disease characterized by ulcerative genital lesions that is endemic in many less developed regions
• Inguinal canal, a passage in the anterior abdominal wall which in men conveys the spermatic cord and in women the round ligament
• Inguinal falx, the conjoined tendon of the obliquus internus and transversus muscles
• Inguinal hernia, a protrusion of abdominal-cavity contents through the inguinal canal
  • Direct inguinal hernia, a type of inguinal hernia with a sac that is medial to the inferior epigastric vessels
  • Indirect inguinal hernia, a hernia that results from the failure of the embryonic internal inguinal ring after the testicle has passed through it
• Inguinal ligament, a ligament that runs from the pubic tubercle to the anterior superior iliac spine
• Inguinal lymph node a type of lymph node in the inguinal region
  • Deep inguinal lymph nodes, three to five deep lymph nodes that are located medial to the femoral vein and under the cribriform fascia
  • Superficial inguinal lymph nodes, ten superficial lymph nodes that form a chain immediately below the inguinal ligament
• Inguinal orchiectomy, a surgical procedure to remove a testicle
• Inguinal ring, the two openings of the inguinal canal
  • Deep inguinal ring, the entrance to the inguinal canal
  • Superficial inguinal ring, a triangular opening that forms the exit of the inguinal canal
• Inguinal triangle, a region of the abdominal wall, also known by the eponym Hesselbach's triangle
• Lateral inguinal fossa, a shallow concave stretch of peritoneum on the deep surface of the anterior abdominal wall
• Medial inguinal fossa a depression located within the inguinal triangle on the peritoneal surface of the anterior abdominal wall
• Reflected inguinal ligament, a triangular layer of tendinous fibers formed by the medial fibers of the external abdominal oblique aponeurosis
