The second gentleman or second lady of the United States (SGOTUS or SLOTUS) is the informal title held by the spouse of the vice president of the United States, concurrent with the vice president's term of office. Coined in contrast to "first lady" – albeit used less commonly – the title "second lady" was apparently first used by Jennie Tuttle Hobart (wife of Garret Hobart, vice president 1897–1899) to refer to herself. The first second gentleman of the United States is Doug Emhoff, the husband of Kamala Harris, the current vice president and first female in the position, since January 20, 2021.^[1]

Twelve second ladies have gone on to become first ladies during their husbands' terms as president. The first to do this was Abigail Adams, who was married to John Adams, who was the first vice president from 1789 to 1797 and then the second president from 1797 to 1801. Thus, Abigail was the first second lady and the second first lady. The most recent to do this is Jill Biden, who is married to Joe Biden, the 47th vice president from 2009 to 2017 and then the 46th president since 2021.

Since the 1970s, the vice presidential official residence is One Observatory Circle.
