There's not only one expression but since there's no context, 죄송합니다 is the most basic translation for "Excuse me".

'excuse me ' will be used differently depend on situation Hyejeong explained well but excuse me has another meaning also 실례할께요 ( in the street ,subway,bus or somewhere else ,you say 실례할께요 or 실례하겠습니다 when you walk through crowd.)

실례할게요. (not 께요 in written but 께요 in pronunciation.) 실례합니다. 실례하겠습니다. These are commonly used for 'excuse me'. The other examples as a follwoing Wait a minute, 잠시만요 I am sorry, 죄송합니다 or 미안해요 I beg your pardon, 뭐라고 말씀하셨어요? What? 뭐라고?
