Pavlov married Seraphima Vasilievna Karchevskaya on 1 May 1881. Seraphima, called Sara for short, was born in 1855. They had met in 1878 or 1879 when she went to St. Petersburg to study at the Pedagogical Institute. In her later years, she suffered from ill health and died in 1947.{{citation needed|date=May 2024}}

The first nine years of their marriage were marred by financial problems; Pavlov and his wife often had to stay with others to have a home and, for a time, the two lived apart so that they could find hospitality. Although their poverty caused despair, material welfare was a secondary consideration. Sara's first pregnancy ended in a miscarriage. When she conceived again, the couple took precautions, and she safely gave birth to their first child, a boy whom they named Mirchik; Sara became deeply depressed following Mirchik's sudden death in childhood.{{citation needed|date=May 2024}}

Pavlov and his wife eventually had four more children: Vladimir, Victor, Vsevolod, and Vera.<ref name=nobelbio/> Their youngest son, Vsevolod, died of [[pancreatic cancer]] in 1935, only one year before his father.<ref>{{cite book|last=Babkin|first=B.P.|title=Pavlov, A Biography|year=1949|publisher=The University of Chicago Press|location=Chicago and London|pages=27–54|url=https://archive.org/details/pavlovabiography010332mbp|isbn=978-1-4067-4397-5}}</ref>

Pavlov was an atheist. Pavlov's follower E. M. Kreps asked him whether he was religious. Kreps writes that Pavlov smiled and replied: "Listen, good fellow, in regard to [claims of] my religiosity, my belief in God, my church attendance, there is no truth in it; it is sheer fantasy. I was a seminarian, and like the majority of seminarians, I became an unbeliever, an atheist in my school years."<ref>{{cite journal|author=Windholz, George |title=Pavlov's Religious Orientation|journal=Journal for the Scientific Study of Religion|volume=25|issue=3 |year=1986|pages=320–27|doi=10.2307/1386296|jstor=1386296}}</ref>
