Chop the salmon and dill.
Add the cream cheese and ranch seasoning to a small bowl, and stir well until combined.
Divide the mixture evenly between the 4 tortillas, and spread across the entire surface.
Divide the salmon between the tortillas, and then sprinkle dill over them.
Roll the tortilla up tightly, then wrap it in plastic wrap and refrigerate for 1 hour, or until ready to serve.
Once ready to serve, unwrap the tortilla rolls, and slice into one-inch pieces, discarding (or snacking on) the ends.
Arrange on a platter to serve.
