Peter Forsyth Christensen (born December 24, 1952) is an American prelate of the Roman Catholic Church who has been serving as bishop of the Diocese of Boise in Idaho since 2014.

[3] Christensen briefly attended the College of the Redwoods in Eureka, California, but dropped out in 1975 to move with his mother and siblings to Minneapolis-Saint Paul, Minnesota.

In June 1999, Christensen was appointed pastor of Nativity of Our Lord Parish in St. Paul, where he continued traditional practices, such as perpetual Eucharistic adoration.

After receiving a telephone call from Archbishop Pietro Sambi bringing news of his appointment, he "sobbed for about 15 minutes as he had not sought the episcopal office."

[4] On February 2, 2017, police arrested Reverend Thomas Faucher, a retired priest, for possessing and distributing child pornography.

[7] Christensen in 2012 joined the other Wisconsin bishops in warning against the use of Physician (or Provider) Orders for Life-Sustaining Treatment (POLST).

The bishops wrote to “encourage all Catholics to avoid using all such documents, programs and materials.” [8] In January 2014, Christensen announced that the Diocese of Boise would not allow the use of the Common Core curriculum in its schools.
