Ticonderoga II was a passenger vessel owned by the Lake George Steamboat Company to operate on Lake George.

It was refitted for passenger use from a decommissioned U.S. Navy vessel.

Like most ships of her class, she was not named by the Navy and known only by her designation until her refit.

In the 1990s, she was replaced by the Lac Du Saint Sacrement.
