Eureka is a side-wheel paddle steamboat, built in 1890, which is now preserved at the San Francisco Maritime National Historical Park in San Francisco, California. Originally named Ukiah to commemorate the railway's recent extension into the City of Ukiah, the boat was built by the San Francisco and North Pacific Railroad Company at their Tiburon yard. Eureka has been designated a National Historic Landmark and was listed in the National Register of Historic Places on April 24, 1973. She is the largest existing wooden ship in the world.
