Anders Wiberg (17 July 1816 – 5 November 1887) was a preacher, missionary, and leader of the early Swedish Baptist movement.

Wiberg, like fellow Lutheran-turned-Baptist-pioneer Gustaf Palmquist, was a friend of pietist preacher Carl Olof Rosenius.

Wiberg has been called the "pivotal link to the New World" and "in some ways a piece of ideological blotting paper" due to his connections with so many key figures in the Reader movement.

[5] After a visit to preacher Johann Gerhard Oncken in Hamburg in 1851, Wiberg came to agree with Baptist teachings regarding baptism.

[8] Wiberg returned to Sweden in 1855 to find his writings had contributed to the movement's growth; there were now 500 Swedish Baptists, with 800 to 1000 formal conversions a year.

Speakers at the second conference included key Baptist figures Julius Köbner, John Howard Hinton, and Edward Steane.
