Jalesveva Jayamahe Monument, Naval monument in Semampir, Surabaya, Indonesia.

The Jalesveva Jayamahe Monument is a copper statue roughly 30 meters (about 100 feet) tall showing a navy officer in ceremonial uniform holding a sword, standing atop a roughly 30-meter (about 100-foot) base building near Tanjung Perak Port in Surabaya. The figure faces the harbor basin and doubles as a lighthouse, offering guidance to passing ships.

Construction began in 1993 under the Indonesian Navy Chief of Staff, Admiral Muhamad Arifin, and the monument was designed by sculptor I Nyoman Nuarta. It was built to embody the navy's Sanskrit motto Jalesveva Jayamahe, "On the waters we are victorious."

The name comes from the Indonesian Navy's Sanskrit motto Jalesveva Jayamahe, rendered on the tower in blue letters and translated as "On the waters, we are victorious" or "Our Glory is at the Seas". The statue wears the Ceremonial Service Dress and carries a sword of honour, details a visitor can pick out from below.

The monument stands in Semampir, Surabaya, near Tanjung Perak Port, and its tower serves as a lighthouse for ships entering or leaving the port. Visitors view the statue and tower from the surrounding area; the sources do not mention public access inside the tower or an ascent.

The monument's name comes from the Indonesian Navy's Sanskrit motto Jalesveva Jayamahe, meaning "On the waters, we are victorious." The statue stands 60.6 meters tall, about the same height as the adjacent building, and its base doubles as a lighthouse for ships heading to or from Tanjung Perak and Koarmada II harbours.
