Sam & Cat is an American teen sitcom created by Dan Schneider that aired on Nickelodeon from June 8, 2013, to July 17, 2014. It is a spin-off of iCarly and Victorious, two TV shows that Schneider also created. The series stars Jennette McCurdy as Sam Puckett from iCarly, and Ariana Grande as Cat Valentine from Victorious. The girls meet by chance during a bizarre adventure and become roommates, then start a babysitting business to earn extra money.

First announced with a pilot order in August 2012, Nickelodeon picked up the pilot to series in November. Production began on a 20-episode order in January 2013. Following high ratings in its initial episodes, Nickelodeon doubled the episode order to 40 in July. In March 2014, Nickelodeon executive told advertisers that the series had been renewed for a second season.

In April 2014, Nickelodeon announced that the series would go on a production hiatus. Following speculation from media outlets, the network confirmed on July 13 that Sam & Cat had been cancelled and the last episode aired on July 17, 2014.

Ever since Carly Shay moved to Italy with her father, Sam Puckett has been touring the West Coast on her motorcycle and stops in Venice, Los Angeles. She witnesses Cat Valentine being thrown into the back of a garbage truck and rescues her. They become friends and Cat convinces her to become roommates. Rather than getting traditional after-school jobs to make money, Sam and Cat develop an after-school babysitting business called "Sam and Cat's Super Rockin' Fun Time Babysitting Service", which leads them into a series of wacky adventures. Besides Nona, other people involved in their lives are Dice, their next door neighbor who is notorious for helping people for money, and Goomer, a dim-witted professional MMA fighter whom Dice manages.

Coincidentally, co-stars Jennette McCurdy and Ariana Grande share a birthday, with McCurdy being born on June 26, 1992 and Grande a year later, on June 26, 1993.

The first season was originally planned to have 20 episodes, but on July 11, 2013, Nickelodeon doubled the order to 40. However, only 36 were produced, and 35 were aired (two produced episodes were merged into a single special for airing).

In August 2012, Nickelodeon announced that Dan Schneider, the creator of iCarly and Victorious, would be making a spin-off of both shows called Sam & Cat, starring Jennette McCurdy and Ariana Grande as their respective characters starting a babysitting service together, and ordered the pilot episode. The series was then picked up for 20 episodes in November, with the premiere planned for 2013. In her 2022 memoir I'm Glad My Mom Died, McCurdy revealed that when she entered a development deal to star in the series months earlier, in 2012, the show was planned as Just Puckett, a series following Sam as a school counselor. After she was already attached, the show was redeveloped as a joint spin-off with Grande.

Production began in January 2013, and on June 8, 2013, Sam & Cat premiered in the United States. Several weeks later, on July 11, Nickelodeon doubled the season one order of 20 episodes, to 40. Filming was scheduled to resume in early September 2013 to finish the second half of the first season.
