The Institute of Governmental Advocates (IGA) is a voluntary, non-partisan association representing the leading professional lobbyists and lobbying firms in California's Capitol.

Our primary mission is to protect and defend the First Amendment rights of lobbyists to advocate on behalf of their clients in California's Legislature, the Governor's Office, and the agencies, boards, and commissions of the Executive Branch of state government.

IGA members subscribe to a voluntary code of conduct and professional ethics that go beyond what is required under the Fair Political Practices Act. IGA also works instill core values of integrity, honesty, and professionalism among the members of the "Third House" and pass along those values to the next generation of lobbyists.
