"Fast Food Song" is a song made famous by the British-based band the Fast Food Rockers, although it existed long before they recorded it, as a popular children's playground song. The chorus was based on the Moroccan folk tune "A Ram Sam Sam". It mentions the fast food restaurants McDonald's, Kentucky Fried Chicken and Pizza Hut.

It was released in June 2003 as the lead single from their album It's Never Easy Being Cheesy. The song was highly successful in the United Kingdom, reaching number two on the UK Singles Chart and number one on the Scottish Singles Chart. It was also placed number 36 in the year end chart of 2003. The song also achieved minor chart success worldwide and reached number 24 on the Irish Charts and number 56 on the Australian ARIA Singles Chart. The song was co-written and produced by Mike Stock.
