A bundled tube fuel nozzle assembly includes a fuel injector and a tube bundle comprising a plurality of tubes that provide for fluid communication through a forward plate, a fuel plenum and an aft plate of the bundled tube fuel nozzle assembly. Each tube includes an inlet defined at an upstream end of the tube and an outlet defined at a downstream end of the tube. The fuel injector is disposed upstream from the inlets of each of the tubes. The upstream end of each tube is noncircular and includes at least one side portion that abuts a complementary upstream end side portion of an immediately adjacent tube of the plurality of tubes. The downstream end of each tube may be circular and is spaced apart from the downstream ends of immediately adjacent tubes of the plurality of tubes.
