Charles X Gustav had only one legitimate child by [[Hedwig Eleonora of Holstein-Gottorp]]: his successor [[Charles XI of Sweden|Charles XI]]{{sfn|Granlund|2004|p=56}} (1655–1697, reigned 1660–1697).

Before his marriage, his mistress [[Märta Allertz]] gave birth to their well-known son [[Gustaf Carlson, Count of Börringe and Lindholm|Gustaf Carlson]] (1647–1708), who became Count of [[Börringe Abbey|Börringe]] and [[Lindholmen Castle]] in [[Scania]].

There are credible theories suggesting that Charles X Gustav, before marrying Hedwig Eleonora (but not after), also sired several more children of whom some names are known:<ref>[[Ulf Sundberg]] in ''Kungliga släktband'' {{ISBN|91-85057-48-7}} pp. 123–124 & 278</ref> by Baroness Ludmila Jankovska von Lažan (1615–1655) a son Charles (Carolus Wenzeslaus) [[Jankovský z Vlašimi]] (1644–1684), who became Baron of Château Rešice in Moravia;<ref>Sixtus Bolom in ''Tajemství Jankovských z Vlašimi a na Bítově'' {{ISBN|978-80-7268-527-1}} p. 91</ref> by Walbor Staffansdotter son Nils Karlsson (who strongly resembled his father); by Sidonia Johansdotter son Samuel Karlsson and by an unknown woman daughter Anna Karlsdotter.
