In the United States the eleventh grade (or Grade 11 in some places) is the 11th school year after kindergarten; students are usually 16–17 years old, but may be as old as 20. It is typically the third, and second-to-last year in high school. Many students take the SAT in the second half of their 11th-grade year. In American naming, it is called the high school junior year, and the term 'junior' can be applied to anyone in a penultimate year at an educational establishment.

In the United States, in mathematics, students usually take Algebra II, Trigonometry, Pre-Calculus, or Calculus. A college-preparatory curriculum would also include American literature as part of the English course.

For social studies curriculum in America, eleventh graders are usually taught American history.

While normally followed by twelfth grade, some colleges will accept excelling students out of this grade as part of an early college entrance program. In Quebec grade 11 (sec. 5) is the final year of secondary education, followed by Cegep.
