Yes, hexatriene has multiple resonance structures.

Explanation:

The structure of hexa-1,3,5-triene is

Hexatriene
(from www.chemsynthesis.com)

We can draw many resonance contributors for hexatriene.

CH2=CH-CH=CH-CH=CH2CH2-+CH-CH=CH-CH=CH2CH2-CH=CH-+CH-CH=CH2etc.

All but the first contributor have a separation of charge, so they are high-energy contributors and relatively unimportant.

Hexa-1,3,5-triene has only one important resonance contributor.
