This is a list of Knights Commander of the Most Exalted Order of the Star of India from 1867 until 1947, when the order ceased to be awarded. It was the second highest class of the Order of the Star of India, following on from the highest class of Knights Grand Commander. Recipients used the post-nominal initials "KCSI" and prefixed "Sir" to their forenames. Wives of Knights Commanders could prefix "Lady" to their surnames. Such forms were not used by peers and Indian princes, except when the names of the former were written out in their fullest forms.
