Hot Spot is a musical with the book by Jack Weinstock and Willie Gilbert, lyrics by Martin Charnin, music by Mary Rodgers, and additional lyrics and music by Stephen Sondheim. It had a brief run on Broadway in 1963. The musical is a political satire.

Hot Spot is an infra-red imaging system used in cricket to determine whether the ball has struck the batsman, bat or pad. Hot Spot requires two infra-red cameras on opposite sides of the ground above the field of play that are continuously recording an image. Any suspected snick or bat/pad event can be verified by examining the infrared image, which usually shows a bright spot where contact friction from the ball has elevated the local temperature. Where referrals to an off-field third umpire are permitted, the technology is used to enhance the on-field umpire's decision-making accuracy. Where referrals are not permitted, the technology is used primarily as an analysis aid for televised coverage.

"Hot Spot" is the first single released from American female hip-hop artist Foxy Brown's second album Chyna Doll. It was released in the United States on October 26, 1998. The single was produced by Murder Inc founder Irv Gotti and co-producer Lil' Rob, with lyrics written by Foxy Brown and hip-hop artist Jay-Z. The single received a short-lived buzz and peaked at 91 on the Billboard Hot 100. It was the last time Foxy Brown would make her appearance on the Billboard Hot 100 as a solo artist.

In veterinary medicine, a "hot spot" (or acute pyoderma, acute moist pyotraumatic dermatitis (AMPD)) is one of the many names for a raw, painful, irritated skin lesion that results in and worsens from a pet (such as a dog or a cat) constantly biting, scratching, chewing, and licking an area of its skin that is irritated or itchy. If it is covered by the dog's hair, the hair holds in the moisture and further irritates it.

Pyotraumatic dermatitis is an acute, rapidly developing surface bacterial skin infection that occurs as a result of self-inflicted trauma. These lesions are created when the animal licks, chews, scratches and rubs a focal area of skin in response to an itchy (pruritic), painful stimulus.

As the lesion grows, secondary infection from opportunistic bacteria can occur, causing more discomfort and leading the pet to scratch and chew even more.

Other names include wet eczema, moist eczema, summer sores, acute moist alderman, acute moist dermatitis, pyo traumatic dermatitis, or acute pyo traumatic dermatitis. As the nickname "summer sores" suggests, hot spots are more common in the summer; however, the ailment can occur at any time of the year. Many pets that develop them have allergies; they are particularly common in pets with flea allergies. However, any sort of irritation to the skin can result in a hot spot.

A hot spot in computer science is most usually defined as a region of a computer program where a high proportion of executed instructions occur or where most time is spent during the program's execution (not necessarily the same thing since some instructions are faster than others).

If a program is stopped randomly, the program counter (the pointer to the next instruction to be executed) is frequently found to contain the address of an instruction within a certain range, possibly indicating code that is in need of optimization or even indicating the existence of a 'tight' CPU loop. This simple technique can actually be used as a method of detecting highly used instructions although somewhat more sophisticated methods, such as instruction set simulators or performance analyzers, achieve this more accurately and consistently.
