A crossbencher is an independent or minor party member of some legislatures, such as the British House of Lords and in the Parliament of Australia. They take their name from the crossbenches, between and perpendicular to the government and opposition benches, where crossbenchers sit in the chamber; compare frontbencher and backbencher.

Crossbench members of the British House of Lords are not aligned to any particular party. These include the judges appointed under the Appellate Jurisdiction Act 1876. In addition, former Speakers of the House of Commons (such as Lord Martin and Baroness Boothroyd) and former Lord Speakers of the House of Lords (such as Baroness Hayman), who by convention are not aligned with any party, also sit as Crossbenchers. There are also some non-affiliated members of the House of Lords who are not part of the crossbencher group; this includes some officers, such as the Lord Speaker, and others who are associated with a party but have had the whip withdrawn. Although non-affiliated members, and members of small parties, sometimes sit on the physical crossbenches, they are not members of the Crossbench parliamentary group.
By their own description, many Crossbenchers are known for bringing specialist knowledge to the House, since most Crossbenchers have been created peers for reasons other than party or political affiliation. Since 2000, the House of Lords Appointments Commission has nominated a total of 59 non-party-political life peers (as of July 2012), who joined the House of Lords as Crossbenchers.
As of 1 October 2011, there are 177 Crossbenchers in the House of Lords—making them the third largest grouping after the Labour and Conservative parties. Of this total, 146 are life peers and 31 are hereditary peers (including a royal office-holder). From April 2007 to 2009, the number of Crossbenchers was higher than the number of Conservatives in the Lords for the first time.
Although the Lords Spiritual (archbishops and senior bishops of the Church of England) also have no party affiliation, they are not considered Crossbenchers and do not sit on the crossbenches, their seats being on the Government side of the Lords Chamber.
The Crossbenchers do not take a collective position on issues, so have no whips; however, they do elect from among themselves a convenor for administrative purposes, and to keep them up-to-date with the business of the House. The current convenor is Lord Laming, who took office in September 2011. While convenors are not part of the "usual channels" (i.e., the party whips who decide the business of the House), they have been included in their discussions in recent years.
The following have served as Convenor of the Crossbenchers:
- 1968–1974: Lord Strang
- 1974–1995: Baroness Hylton-Foster
- 1995–1999: Lord Weatherill (Alternate Convenor 1993–1995)
- 1999–2004: Lord Craig of Radley
- 2004–2007: Lord Williamson of Horton
- 2007–2011: Baroness D’Souza
- 2011–present: Lord Laming
The term refers to both independent and minor party members in various Parliaments of Australia.
The present Australian Parliament, as elected at the 2010 election, is the 43rd Federal Parliament since Federation. It is the first hung parliament in the House of Representatives since the 1940 election, with Labor and the Coalition winning 72 seats each of 150 total. Six crossbenchers hold the balance of power: Greens MP Adam Bandt and independent MPs Andrew Wilkie, Rob Oakeshott and Tony Windsor declared their support for Labor on confidence and supply, independent MP Bob Katter and National Party of Western Australia MP Tony Crook declared their support for the Coalition on confidence and supply. The resulting 76–74 margin entitled Labor to form a minority government.
In the 76-seat Senate, where no party tends to have a majority of seats, the Greens gained the sole balance of power with a total of nine of eleven crossbench seats. Labor holding 31 seats, they require an additional eight non-Labor votes to pass legislation. The Coalition holds 34 seats, while the two remaining seats are occupied by independent Senator Nick Xenophon and Democratic Labor Party Senator John Madigan.
