Jānis Matulis (21 February 1911 – 19 August 1985) was a Latvian prelate of the Evangelical Lutheran Church of Latvia and Archbishop of Riga from 1969 to 1985.

Matulis was born on 21 February 1911 in Kaluga, in the Russian Empire in present-day Russia, to a family of servants.

From 1936 to 1943 he studied theology on a scale cum laude, by the Faculty work "Kāds EVED-JAHVE problēmas atrisinājuma mēģinājums".

Sven Danell, the Bishop of Skara in Sweden, consecrated him on 14 September 1969 and consequently restored the apostolic succession in the Latvian church.

Archbishop Mutalis is mostly remembered for his decision to ordain women to the priesthood in the Church of Latvia in 1975.
