The Cataldo Mission, also known as the Mission of the Sacred Heart, is a historic Catholic mission located in Cataldo, Idaho, United States. It was established in the mid-19th century by Jesuit missionaries, who were seeking to convert the Native American tribes in the area to Catholicism.

The mission is notable for its architectural style, which combines elements of both European and Native American design. It is made of adobe brick and features a distinctive bell tower and a large, open chapel.

The mission played a significant role in the early history of Idaho and the surrounding region. It served as a center of religious and cultural activity for the Native American tribes, as well as a waystation for travelers and settlers moving westward. It was also used as a hospital and a school, and played a key role in the development of the state's education system.

Today, the Cataldo Mission is a popular tourist attraction and is listed on the National Register of Historic Places. It is open to the public and hosts a variety of events and activities throughout the year.
