On 31 May 1700, he married his first wife, [[Princess Luise Dorothea of Prussia|Luise Dorothea]], Princess of [[Kingdom of Prussia|Prussia]] (1680–1705), daughter of [[Frederick I of Prussia]] (1657–1713) and [[Elisabeth Henriette of Hesse-Kassel]] (1661–1683). Luise Dorothea died in childbirth in December 1705.

His second wife, whom he married in 1715, was [[Ulrika Eleonora, Queen of Sweden|Ulrika Eleonora]], Princess of [[Kingdom of Sweden|Sweden]] (1688–1741), daughter of [[Charles XI of Sweden]] (1655–1697) and of [[Ulrika Eleonora of Denmark]] (1656–1693). Ulrika suffered two miscarriages, one in 1715 and another in 1718, after which there are no further recorded pregnancies.

Frederick I had three extramarital children with his mistress [[Hedvig Taube]]:
* [[Frederick William von Hessenstein]] (1735–1808).
* [[Charles Edward von Hessenstein]] (1737–1769).
* Hedwig Amalia von Hessenstein (1743–1752).

After the death of Hedvig Taube, his official mistress was the noblewoman [[Catharina Ebba Horn]] (1720–1781), whom he gave the title and recognition of Countess (from 1745).

Thus, the Hessian line in Sweden ended with him and was followed by that of [[House of Holstein-Gottorp (Swedish line)|Holstein-Gottorp]]. In [[Landgraviate of Hesse-Kassel|Hesse-Kassel]], he was succeeded by his younger brother [[William VIII, Landgrave of Hesse-Kassel|William VIII]], a famous general.
