Ulrik Adolf Holstein, Greve til Holsteinborg (14 April 1664 – 21 August 1737) was a Danish nobleman and statesman.

His father, Adam Christopher von Holstein (1631-1690) owned Netzeband and Buchholtz in Mecklenburg; his mother was Cathrine Christine Reventlow of Futterkamp (1647-1704).

In 1679 he became a page to Crown Prince Frederick and found favour, becoming a noble (freiherr) in 1700.

He was removed from court in 1703 after attempting to dissuade the King from marrying royal mistress Elisabeth Helene von Vieregg (1679–1704).

He became a bailiff in Flensburg, was appointed Privy council (Geheimrat) in 1703 and held this office for a number of years.
