Answer:

phenolphthalein

The pH range of phenolphthalein is about 8.3 to 10.0, but the titration curve is so steep at the equivalence point that phenolphthalein makes a good indicator. For a strong base-weak acid titration, the equivalence point is probably near pH 9. Phenolphthalein is great for this titration.
