Johan Magnus Almqvist (September 6, 1799 – October 9, 1873) was a Swedish theologian and parliamentarian.

In 1830, Almqvist became vicar of Skärstad Church near Jönköping and remained so until his death.

As a politician, he was a liberal and belonged to the opposition party within the clergy against its conservative majority.

He was a "staunch supporter" of Louis Gerhard De Geer, the country's first prime minister, at the 1865 Riksdag.

Almqvist also worked for the cause of temperance and was on the 1859–1860 Riksdag committee on spirits.
