Ek Do Teen is a 1953 Hindi comedy film produced and directed by Roop K. Shorey.

It stars Motilal, Meena Shorey, Yashodra Katju, Majnu and Iftekhar. The story, screenplay and dialogues were written by Krishan Chander. The story has some similarity to Somerset Maugham's Facts Of Life. The music was composed by Vinod and the lyricist was Aziz Kashmiri.

The film was a follow-up to Ek Thi Ladki (1949), which was directed by Roop K. Shorey and starred his wife Meena Shorey with Motilal. Meena Shorey emerged as a fine comedian and was called the "Lara Lappa" girl from the song composed by Vinod and picturised on her in Ek Thi Ladki. However, Ek Do Teen did not do as well and was a turning point in Shorey's career.

Ek do teen (one two three) is the number of caveats passed on by Motilal's father to him before the father dies. The hero experiences each one of the three cautions only to find his father's dying homily to be true.
