1962 South Australian state election
State elections were held in South Australia on 3 March 1962. All 39 seats in the South Australian House of Assembly were up for election. The incumbent Liberal and Country League led by Premier of South Australia Thomas Playford IV defeated the Australian Labor Party led by Leader of the Opposition Frank Walsh.

Background
The Playford government, in power since 1938, went into the 1962 elections in a precarious position.  At the time the writs were issued, South Australia was dogged by a massive recession.  This led observers to think that Labor would finally have a chance at power.  Longtime opposition leader Mick O'Halloran had died suddenly in 1960, and Labor was led into the election by former deputy leader Frank Walsh.

The Labor opposition won in excess of 54 percent of the statewide two-party vote, however the LCL retained government with the assistance of the Playmander − an electoral malapportionment in which there were two country seats for every one seat in Adelaide. This system resulted in Labor being denied government in 1944, 1953 and 1968 despite winning clear statewide two-party majorities.

While O'Halloran had despaired of ever becoming Premier, Walsh made a concerted effort to end the LCL's three-decade grip on government. Knowing that the Playmander made a statewide campaign fruitless, Walsh instead decided to target marginal LCL seats.  In the election, Labor scored 54.3 percent of the two-party vote to only 45.7 percent for the LCL, a 4.6 percent swing to Labor. In most other states, this would have made Walsh premier with a landslide majority. However, due to the Playmander, the election resulted in a hung parliament. Labor won 19 seats, one seat short of a majority, while the LCL won 18 seats, two seats short of a majority. Even with this to consider, speculation was rampant on election night that Playford's long tenure was finally over.

Labor took the seats of Chaffey and Unley off the LCL (and later Glenelg and Barossa at the 1965 election). The LCL won only four metropolitan seats – Burnside, Glenelg, Mitcham and Torrens.

However, Playford refused to concede, instead saying he would wait to see how the chamber lined up once the legislature reassembled. Both crossbench independent MPs, Tom Stott and Percy Quirke, held the balance of power. They announced confidence and supply support for an LCL minority government with a bare one-seat parliamentary majority. Stott became Speaker of the South Australian House of Assembly following the election, while Quirke joined the LCL and entered the ministry in 1963. Walsh lobbied Governor Edric Bastyan not to reappoint Playford, to no avail.

The furore over the 1962 election illustrated how distorted the Playmander had become. By this time some two-thirds of the state's population resided in and around Adelaide, but they only elected one-third of the members of the legislature. In many cases, a rural vote was worth at least double a vote in Adelaide. In one of the more extreme cases, the rural seat of Frome had 4,500 formal votes in 1968, while at the same election the metropolitan seat of Enfield had 42,000 formal votes.
