David "Dave" Pahanish is an American singer-songwriter. He co-wrote the No. 1 Billboard country music singles "Do You Believe Me Now” by Jimmy Wayne, "American Ride" by Toby Keith, and "Without You" by Keith Urban. Pahanish has also had songs recorded by Tim McGraw.

A native of southwestern Pennsylvania, Pahanish regularly performed folk rock on the stages of Pittsburgh for over 15 years. His songs appeared in television series and he collaborated with Nashville-based songwriter Michael Garvin.

Pahanish relocated from California, Pennsylvania, to Nashville in late 2006. Within weeks, he was offered three music publishing deals, and signed with 3 River Publishing, owned by songwriters Hillary Lindsey, Dallas Davidson, and Cole Wright. Pahanish wrote the majority of songs on Moon Township country singer Sarah Marince's debut CD, Somebody Like You. He also co-wrote and co-produced the Top 40 Billboard Hot Country Songs charting single, "I Will", by Jimmy Wayne. Pahanish co-wrote the single, "Without You", with Joe West, recorded by Keith Urban on his 2010 album, Get Closer. Urban chose the song because of how closely the lyrics and message fit in with his own life, stating: "It's the most autobiographical song I never wrote." Pahanish wrote the song after meeting his wife’s family for the first time, without realizing any similarities to Urban’s life. The song became Urban's 12th No. 1 single and Pahanish and West's third No. 1 song. Two of Pahanish's songs were recorded by Tim McGraw for his 2012 album, Emotional Traffic.
