Tinea cruris, also known as jock itch, is a type of fungal infection of the skin of the groin region. Symptoms typically include an itchy, red, and raised rash with a scaly and well-defined curved border. Most commonly this occurs over the upper inner thighs.

It is cause by a group of fungi known as dermatophytes. Risk factors include excessive sweating, tight fighting clothing, contact sports, diabetes, and poverty. It may spread to the groin from athletes foot, a fungal nail infection, or an infected towel or other clothing. Diagnosis may be confirmed by microscopy or culturing of skin scrapings. Similar conditions include candidal intertrigo, erythrasma, inverse psoriasis and seborrhoeic dermatitis. It is a type of dermatophytosis.

Treatment is typically with antifungal creams which are particularly effective if started soon after symptoms onset. In more significant cases antifungals, such as terbinafine, by mouth may be used. Steroid cream may speed symptom improvement. Prevention of recurrences include treating other fungal infections and taking measures to avoid moisture build-up by keeping the groin dry, avoiding tight clothing, and losing weight if obese.

Tinea cruris is common. Males are affected more often than females and it occurs more commonly in hot-humid climates. Children; however, are rarely affected. Tinea was first described in 30 AD by Aulus Cornelius Celsus.
