"(How Much Is) That Doggie in the Window?" is a popular novelty song written by Bob Merrill in 1952. It was adapted from a well-known Victorian music hall song. The best-known version of the song was recorded by Patti Page on December 18, 1952 and released by Mercury Records as catalog number 70070, with the flip side being "My Jealous Eyes." It reached #1 on both the Billboard and Cash Box charts in 1953. However, Mercury, the record label which distributed Patti Page's recordings at the time, had poor distribution in the United Kingdom. Therefore, a recording by Lita Roza was the one most widely heard in the UK, reaching #1 on the UK Singles Chart in 1953. It also gave Roza the title of being the first British woman to have a number one hit in the UK chart.

The song's lyrics tell the story of a young woman who has to go on a trip to California, and wants to buy a dog for her "sweetheart" so that he will not be lonely, and so that any robbers will be scared away.

The song has also been covered by many groups and is available on many children songs CDs and is considered as Children's music in many countries. It can also be found on many musical toys made since the late 1960s. For example, a Sankyo music box made in the 1970s played the song, as do many musical toys manufactured today.
