Dov (Dubi) Seltzer (Hebrew: דב (דובי) זלצר; born 26 January 1932) is a Romanian-born Israeli composer and conductor.

When Seltzer immigrated to Israel at age 15, a musical comedy he had previously written continued to be played for two more years, performed by one of Bucharest's professional youth theaters.

At the recommendation of his teacher, the pianist Frank Pelleg, Seltzer was awarded a scholarship to continue his musical studies at the Conservatories in Haifa and later on in Tel Aviv.

He composed, arranged, and played accordion for the Israeli troupe Oranim Zabar, and was married to their lead singer, Geula Gill.

During his military service, Seltzer received a special grant from the army to pursue studies in composition, harmony and counterpoint with composers Herbert Bruen, Mordechai Seter, and Professor Abel Erlich.
