Do I need to list ALL of my previous employers on job applications?

I am a recent college graduate. It took me a while to complete my degree and I have had a significant number of part time employers in my complete job history. Do I need to list every employer that I have had over my entire job history or can I list just those in the last 5 years?

Follow the directions on the application. Some applications only require the last three employers, some require up to 10 years of employers. Some state "all" some don't.

I know when people only put down what is "relevant" I think they are hiding something. I would much rather have all their non relevant jobs so I can see that they were at least working.
