Deltra I was a German fishing trawler that was requisitioned by the Kriegsmarine in the Second World War for use as a vorpostenboot. She was built in 1920 as Oliva and was renamed Gothmund in that year. She was renamed Otto Telschow in 1933, then Baltrum the next year and Deltra I in 1938.

Requisitioned in 1942, she served as V 1523 Deltra I and V 215 Oliva before being scuttled in 1944. She was raised post-war, repaired and returned to service as the Polish-owned, French-registered fishing trawler Deltra I. Renamed Deltra in 1951, she was scrapped in 1957.
