'''Metil jingga''' adalah [[Indikator asam-basa|indikator pH]] yang sering digunakan dalam [[Titrimetri|titrasi]] karena perubahan warnanya yang jelas dan kontras. Oleh karena ia berubah warna pada pH sedikit asam, maka biasa digunakan dalam titrasi asam. Tidak seperti [[indikator universal]], metil jingga tidak memiliki spektrum perubahan warna yang lengkap, tetapi memiliki titik akhir yang lebih tajam.
