Athens is named after it's patron goddess Pallas Athene, or Athena. Athena won the rights to being patron of the city when she produced the olive tree, beating the salt water spring that Poseidon (her competition who was also vying for patron) created. Thus, the city was named in her honor. That is also why the Parthenon (a temple dedicated to her) is located in the agora of Athens.
