Can someone list monologues for guys please? A monologue that has brought you success or any well known, anything would be nice. Even a website! 
It’s hard to recommend for you without knowing anything about you. It’s also sort of your job to find monologues.
But here are some places to start looking.
- Think about shows you’ve been in – you might be able to use something you’ve already worked on.
- Look at lists of old Tony nominees, “America’s Best Plays” etc., season theater previews (the NYT has one, also seen them in Chicago) to get a sense of what’s out there. You need to find ones that have young-ish characters like you.
- Look at the plays that the schools you’re targeting have done in the past (I’d avoid the ones they’re putting on right now). They often have a lot of age-appropriate roles in them.
- Call the Drama Bookshop in NYC and ask them for recommendations (do it off hours, they get busy on the weekend). You’ll need to be able to tell them a little about what you’re looking for, what type you are, etc.
- Backstage has a service called The Monologuer, which I have not used but might be helpful. http://www.backstage.com/advice-for-actors/resources/monologuer-find-perfect-monologue/
- Think about hiring a coach, either just for monologue selection or for coaching too.
- Ask the theater people you know – directors, teachers, fellow actors, etc – for recommendations.
I hope this might be helpful. It’s a list from Marymount Manhattan of monologues they suggest (and ones that are overdone:)
