Patrick J. Diegnan Jr. (born March 19, 1949) is an American lawyer and Democratic Party politician who has represented the 18th Legislative District in the New Jersey Senate since 2016.

Early life The youngest of seven children born to immigrants from Ireland, Diegnan was born and raised in South Plainfield, attending Sacred Heart Grammar School and then graduating from South Plainfield High School in 1966. Residents of South Plainfield, Diegnan and his wife Anita have been married since 1976 and have two children, Heather and Tara, along with a grandchild.

New Jersey Assembly Diegnan was first elected to represent the 18th District in 2001 replacing Barbara Buono who had been elected to the New Jersey Senate. He was re-elected to seven more two-year terms. Diegnan served in the Assembly as Deputy Speaker (2008-2016) and Parliamentarian (2005-2016), and was Chairman of the Education Committee and a member of the Regulated Professions and Consumer Affairs Committees.

New Jersey Senate Diegnan was selected by local Democratic committee members to receive appointment to the 18th District's Senate seat on May 5, 2016, after previous seat holder Peter J. Barnes III was appointed to a judgeship on the New Jersey Superior Court. Sworn into office on May 9, Diegnan won election to the remainder of the term in November, defeating retired judge and former Middlesex County Freeholder Roger W. Daley.

District 18 Each of the 40 districts in the New Jersey Legislature has one representative in the New Jersey Senate and two members in the New Jersey General Assembly.

Legislative accomplishments Diegnan was the primary sponsor of Assembly Bill 3331, introduced in 2003, which creates the certification of Technology Education for teachers. In 2011, he was the primary sponsor of Assembly Bill 3852, which requires voter approval at the annual school election or by the board of school estimate before a new charter school can be authorized to operate in a district. Under the existing system, the Commissioner of the New Jersey Department of Education can grant charters regardless of community opinion, with Diegnan noting that allowing voters and local boards of education a say in the granting of new schools would "help ensure that the charter schools that are created fit the needs of the community". The bill passed in the Assembly in June 2011 by a 47-17 margin.
