Trpimir II (died c. 935) was a King of Croatia from 928 to 935. He was from the House of Trpimir. Trpimir was probably the son of Duke Muncimir and younger brother of Tomislav.

Following the death of Bulgarian ruler, Symeon, Byzantium no longer needed Croatia's military support and repealed its alliance. Previously, Byzantium relied heavily on the Croats to threaten Symeon from the west. Despite the achievements of King Tomislav in halting Bulgaria's expansion, Byzantium reversed Croatia's supremacy over the Dalmatian thema, which fell once again under its administration. However, Byzantine administration was nominal.

Trpimir's woes did not stop there. Pope Leo VI abolished the Nin Bishopric in 928 and transferred Bishop Grgur to Skradin, in what was seen as a humiliating defeat for pro Slavic proponents in the long running dispute between the Split and Nin Bishoprics.

The "De Administrando Imperio" mentions that in the time of Trpimir Croatia has a significant merchant fleet, that trades across the entire Adriatic Sea.
