Solco Walle Tromp (9, March 1909 - 17, March 1983) was a Dutch geologist and biometeorologist.

Tromp was from 1947 to 1950 Professor of geology at Cairo University. He co-founded the International Society of Biometeorology and published pioneering writings on biometeorology.

Tromp took a deep interest in dowsing and radiesthesia. He conducted experiments and came to the conclusion that dowsing is a real phenomenon due to activity of electromagnetic fields. His views on dowsing were criticized by the scientific community and have been described by critics as an example of pseudoscience.
