Arthur! and the Square Knights of the Round Table

'Arthur! And the Square Knights of the Round Table' is a 1966–1968 Australian animated series based on the legend of King Arthur of Camelot.

The series was produced by Air Programs International and written by Melbourne playwright Alex Buzo and British-born entertainer Rod Hull, with Lyle Martin, Michael Robinson, and John Palmer. The characters included King Arthur, Guinevere, Lancelot, Merlin, the Jester, the Black Knight, and Morgana le Fay. The actors who voiced the character parts in the series included: John Meillon (as "Arthur"), Lola Brooks (as "Guinevere" and "Morgana le Fay"), John Ewart, Kevin Golsby, and Matthew O'Sullivan.

By 1969, the series had been sold for broadcast in the United Kingdom and the United States. In Australia, where it was made and produced, it was sold also to the Australian Broadcasting Commission, for broadcast on the ABC-TV network. Typically it was broadcast on Saturday mornings and initially also, on Monday evenings. As the Australian television industry did not go to colour broadcast until March 1975, viewers saw the series in black and white for the first six years of its Australian transmission.

ABC-TV continued repeated the series for most of the 1970s; its last appearance as children's programming was March 1985.

The series was broadcast in Italy in the early 1970s. French television purchased it for broadcast in 1980-81, supplying a French soundtrack, without the original music. It was broadcast on the French television channel, TF1. In 1993, the series was also being broadcast on German cable television.
