For the 2024-2025 session, the 8th legislative district of the New Jersey Legislature is represented in the New Jersey Senate by Latham Tiver (R, Southampton Township) and in the General Assembly by Andrea Katz (D, Chesterfield Township) and Michael Torrissi (R, Hammonton).^[6]

The legislative district overlaps with 2nd and 3rd congressional districts.

During the 221st Legislature, this is one of two legislative districts in the state (along with the 30th) where both parties hold at least one seat.

During the period of time after the 1964 Supreme Court decision in Reynolds v. Sims and before the establishment of a 40-district legislature in 1973, the 8th district encompassed the entirety of Somerset County.^[7][8][9] During the three Senate elections held during this period (1965, 1967, and 1971), Republicans won all three races. Incumbent Senator William E. Ozzard won reelection in 1965 for a two-year term (though he resigned on July 10, 1967^[10]), while for the next two elections, Raymond Bateman was victorious for both elections.^[7][11][12]

In the terms from 1967 until 1973, the 8th district sent two members to the General Assembly. In all elections for two-year terms, Republicans won both seats. John H. Ewing was one victor in the three regular elections (1967, 1969, 1971), while Webster B. Todd Jr. (son of Webster B. Todd, brother of Christine Todd Whitman) served one term from 1968 until 1970, Millicent Fenwick was elected in 1969 and 1971, but resigned on December 14, 1972, to become head of the New Jersey Division of Consumer Affairs, and Victor A. Rizzolo was elected in a special election on January 30, 1973, to complete her term.^{[11][13][12][14][15]}

When the Legislature was switched to 40 equal-population districts statewide, the 8th district created for the 1973 elections was an uncompact district in Burlington, Ocean, Monmouth, and Mercer counties. With the Keith line as a center spine, the district had branches to Medford Township, Manchester Township, Florence Township, Roosevelt, East Windsor Township, and Lawrence Township.^[16] In the 1980s, the 8th became inclusive of most of Burlington County stretching from Washington Township north to Bordentown.^[17] Following the 1990 census, the district expanded out of Burlington County to Camden County (Winslow Township, Waterford Township, and Chesilhurst) and Atlantic County (Hammonton and Folsom) with the Burlington County portion including suburban townships of Medford, Evesham, Moorestown, Mount Laurel, and Southampton.^[18] The 2001 redistricting returned the district to being Burlington only again keeping it through the center of the county.^[19] The 2011 reapportionment brought Hammonton into the district while the 2021 reapportionment brought in more Atlantic County municipalities and removed all Camden County municipalities.^[20] In 2023, Democrats won one assembly seat thereby marking the first time they won a seat through an election since 1973.
