The title of Senior Counsel or State Counsel (post-nominal letters: SC) is given to a senior lawyer in some countries that were formerly part of the British Empire. "Senior Counsel" is used in current or former Commonwealth countries or jurisdictions that have chosen to change the title "King's Counsel" to a name without monarchical connotations, usually related to the British monarch that is no longer head of state, such that reference to the King is no longer appropriate. Examples of jurisdictions which have made the change because of the latter reason include Mauritius, Zambia, India, Hong Kong, Ireland, South Africa, Kenya, Malawi, Singapore, Guyana and Trinidad and Tobago. Jurisdictions which have retained the monarch as head of state, but have nonetheless opted for the new title include some states and territories of Australia, as well as Belize.

Just as a junior counsel is "called to the [Outer] Bar", a Senior Counsel is, in some jurisdictions, said to be "called to the Inner Bar". Senior Counsel may informally style themselves as silks, like their British counterparts. This is the case in Ireland, Australia, Hong Kong and South Africa.
