Elhanan bin Jair (kwa Kiebrania אלחנן בן יערי) alikuwa mtu wa Bethlehemu kwenye mwaka 1000 KK. Anatajwa na Kitabu cha Pili cha Samueli 21:19 kama muuaji wa jitu Goliathi, Mfilisti wa mji wa Gath.

Tofauti hiyo inatokana na jinsi vitabu hivyo viwili vilivyotungwa kwa kukusanya mapokeo yoyote juu ya mwanzo wa Ufalme wa Israeli bila kuyachambua. Goliathi anatajwa pia katika Qur'an (2: 247–252).
