19 Kids and Counting (formerly 17 Kids and Counting and 18 Kids and Counting) is an American reality television series that aired on the cable channel TLC for seven years until its cancellation in 2015. The show features the Duggar family: parents Michelle and Jim Bob Duggar and their 19 children – nine daughters and ten sons – all of whose names begin with the letter "J". During the duration of the show, two children were born, three children were married, and four grandchildren were born.

The show focuses on the life of the Duggar family, who are devout independent Baptists, and frequently discusses values of purity, modesty and faith in God. The Duggars avoid birth control, saying they have decided to allow God to determine the number of children they have. All of the children are homeschooled and access to entertainment such as movies and television is limited. They practice chaperoned courtship, in which a couple becomes acquainted only in a group setting. The values presented on the show have been associated with the Quiverfull movement, which has been described as promoting strict family conformity, male hierarchies and subservient roles for women. The Duggars have stated that they are not associated with the Quiverfull movement. However, in an article formerly published on their website titled "Why Have Such a Large Family?", the Duggars reference Psalms 127:3-5, from which the Quiverfull movement name comes. Moreover, in 2001, Jim Bob and Michelle were interviewed for an article published on a Quiverfull affiliated website. The Duggar family has also been connected with the Institute in Basic Life Principles and the Advanced Training Institute, both of which were founded by Bill Gothard.

The series began on September 29, 2008, and concluded on May 19, 2015. The show was TLC's most popular, averaging 2.3 million viewers per new episode in Season 10 and scoring in the Nielsen "Cable Top 25".

On May 22, 2015, TLC suspended the series when the Duggars' eldest son Josh publicly apologized for having "acted inexcusably" following reports that he molested five girls, including some of his sisters, by fondling them. These events occurred in 2002 and 2003, when Josh was 14 to 15 years old and prior to the beginning of the show. On July 16, 2015, TLC announced that the show was officially canceled and would not resume production. A spin off show, Counting On, aired in December 2015 and was cancelled in 2021, due to Josh Duggar's arrest for child pornography.
