Life-Line was a Baptist missionary boat used to conduct ministry work in the Coos Bay region of southwestern Oregon, United States, from 1914 to 1923.

Life-Line was designed by George H. Hitchings and built at Coos Bay for Reverend G. L. Hall of the American Baptist Publication Society.

[1] Once complete, "this little ship, under zealot Captain Lund, ran up and down the coast for the Baptist Missionary Society, saving the souls of erring seamen and longshoremen alike.

Life-Line foundered off the coast, just south of Neahkahnie, and Captain Lund and the deckhand swam to shore.
